This high voltage regulator contains an 80V, 0.7A N-Channel Buck Switch. The device is easy to apply and is provided in the VSSOP-8 and the thermally enhanced WSON-8 packages. The regulator is based on a hysteretic control scheme using an on time inversely proportional to Vin. This feature allows the operating frequency to remain relatively constant with load and input voltage variations. The hysteretic control requires no control loop compensation, while providing very fast load transient response. An intelligent current limit scheme is implemented in the LM5007 with forced off time, after current limit detection, which is inversely proportional to Vout. This current limiting scheme reduces load current foldback. Additional protection features include: Thermal Shutdown, Vcc undervoltage lockout, Gate drive undervoltage lockout and Max Duty Cycle limiter. The LM5007 can be applied in numerous applications to efficiently regulate step down higher voltage inputs. This regulator is well suited for 48 Volt Telcom and the new 42V Automotive power bus ranges. Hysteretic Control Circuit Overview The LM5007 is a Buck DC-DC regulator that uses an on time control scheme. The on time is programmed by an external resistor and varies inversely with line input voltage (Vin). The core regulation elements of the LM5007 are the feedback comparator and the on time one-shot. The regulator output voltage is sensed at the feedback pin (FB) and is compared to an internal reference voltage (2.5V). If the FB signal is below the reference voltage, the buck switch is turned on for a fixed time pulse determined by the line voltage and a programming resistor (RON). Following the on period the switch will remain off for at least the minimum off timer period of 300ns. If the FB pin voltage is still below the reference after the 300ns off time, the switch will turn on again for another on time period. This switching behavior will continue until the FB pin voltage reaches the reference voltage level. The LM5007 operates in discontinuous conduction mode at light load currents or continuous conduction mode at heavier load currents. In discontinuous conduction mode, current through the output inductor starts at zero and ramps up to a peak value during the buck switch on time and then back to zero during the off time. The inductor current remains at zero until the next on time period starts when FB falls below the internal reference. In discontinuous mode the operating frequency can be relatively low and will vary with load. Therefore at light loads the conversion efficiency is maintained, since the switching losses decrease with the reduction in load current and switching frequency. The approximate discontinuous mode operating frequency can be calculated as follows: VOUT2 x L F= 1 x 10-20 x RLoad x (RON)2 (1) In continuous conduction mode, current flows continuously through the inductor and never ramps down to zero. In this mode the operating frequency is greater than the discontinuous mode frequency and remains relatively constant with load and line variations. The approximate continuous mode operating frequency can be calculated as follows: VOUT F= 1.42 x 10-10 x RON (2) The output voltage (Vout) can be programmed by two external resistors as shown in Figure 2. The regulation point can be calculated as follows: VOUT = 2.5 x (R1 + R2) / R2 (3) The feedback comparator in hysteretic regulators depend upon the output ripple voltage to switch the output transistor on and off at regular intervals. In order for the internal comparator to respond quickly to changes in output voltage, proportional to inductor current, a minimum amount of capacitor Equivalent Series Resistance (ESR) is required. A ripple voltage of 25mV to 50mV is recommended at the feedback pin (FB) for stable operation. In cases where the intrinsic capacitor ESR is too small, additional series resistance may be added. For applications where lower output voltage ripple is required the load can be connected directly to the low ESR output capacitor, as shown in Figure 2. The series resistor (R) will degrade the load regulation. Another technique for enhancing the ripple voltage at the FB pin is to place a capacitor in parallel with the feedback divider resistor R1. The addition of the capacitor reduces the attenuation of the ripple voltage from the feedback divider Submit Documentation Feedback Copyright © 2003–2013, Texas Instruments Incorporated Product Folder Links: LM5007 5 LM5007 SNVS252F – SEPTEMBER 2003 – REVISED MARCH 2013 www.ti.com High Voltage Bias Regulator The LM5007 contains an internal high voltage bias regulator. The input pin (Vin) can be connected directly to line voltages from 9 V to 75 V. To avoid supply voltage transients due to long lead inductances on the input pin (Vin Pin 8), it is always recommended to connect low ESR ceramic chip capacitor (≊ 0.1µF) between "Vin" pin and "RTN" pin (pin 4), located close to LM5007. The regulator is internally current limited to 10mA. Upon power up, the regulator is enabled and sources current into an external capacitor connected to the Vcc pin. When the voltage on the Vcc pin reaches the regulation point of 7V, the controller output is enabled. An external auxiliary supply voltage can be applied to the Vcc pin. If the auxiliary voltage is greater than 7 V, the internal regulator will essentially shutoff, thus reducing internal power dissipation. VIN L SW R1 R FB + R2 + REF 2.5V VOUT COUT LM5007 Figure 2.

The over-voltage comparator monitors the FB pin versus an internal 2.875V reference (OV_REF). If the voltage at FB rises above OV_REF the comparator immediately terminates the buck switch on time pulse. ON Time generator and Shutdown The on time of the LM5007 is set inversely proportional to the input voltage by an external resistor connected between Ron and Vin. The Ron terminal is a low impedance input biased at approximately 1.5V. Thus the current through the resistor and into the Ron terminal is approximately proportional to Vin and used internally to control the on timer. This scheme of input voltage feed-forward hysteretic operation achieves nearly constant operational frequency over varying line and load conditions. The on time equation for the LM5007 is : Ton = 1.42 x 10-10 x RON / VIN (4) The RON pin of the LM5007 also provides a shutdown function which disables the regulator and significantly decreases quiescent power dissipation. By pulling the RON pin to below 0.7V logic threshold activates the low power shutdown mode. The VIN quiescent current in the shutdown mode is approximately 100µA internal to the LM5007 plus the current in the RON resistor. 7V SERIES REGULATOR VIN VIN ON TIMER RON VIN START RON RON COMPLETE STOP RUN LM5007 Figure 4. Shutdown Implementation Current Limit The LM5007 contains an intelligent current limit off timer intended to reduce the foldback characteristic inherent with fixed off-time over-current protection. If the current in the Buck switch exceeds 725mA the present cycle on time is immediately terminated (cycle by cycle current limit). Following the termination of the cycle a nonresetable current limit off timer is initiated. The duration of the off time is a function of the external resistor (RCI) and the FB pin voltage. When the FB pin voltage equals zero, the current limit off time is internally preset to 17uS. This condition occurs in short circuit operation when a maximum amount of off time is required. In cases of overload (not complete short circuit) the current limit off time can be reduced as a function of the output voltage (measured at the FB pin). Reducing the off time with smaller overloads reduces the amount of foldback and also reduces the initial start-up time. The current limit off time for a given FB pin voltage and RCI resistor can be calculated by the following equation: (5) Submit Documentation Feedback Copyright © 2003–2013, Texas Instruments Incorporated Product Folder Links: LM5007 7 LM5007 SNVS252F – SEPTEMBER 2003 – REVISED MARCH 2013 www.ti.com Applications utilizing low resistance inductors and/or a low voltage drop rectifier may require special evaluation at high line, short circuit conditions. In this special case the preset 17µs (FB = 0V) off time may be insufficient to balance the inductor volt*time product. Additional inductor resistance, output resistance or a larger voltage drop rectifier may be necessary to balance the inductor cycle volt*time product and limit the short circuit current. N-Channel Buck Switch and Driver The LM5007 integrates an N-Channel Buck switch and associated floating high voltage gate driver. This gate driver circuit works in conjunction with an external bootstrap capacitor and an internal high voltage diode. The bootstrap capacitor is charged by VCC through the internal high voltage diode. A 0.01uF ceramic capacitor connected between the BST pin and SW pin is recommended. During each cycle when the Buck switch turns off, the SW pin is approximately 0V. When the SW pin voltage is low, the bootstrap capacitor will be charged from Vcc through the internal diode. The minimum off timer, set to 300ns, ensures that there will be a minimum interval every cycle to recharge the bootstrap capacitor. An external re-circulating diode from the SW pin to ground is necessary to carry the inductor current after the internal Buck switch turns off. This external diode must be of the Ultra-fast or Schottky type to reduce turn-on losses and current over-shoot. The reverse voltage rating of the re-circulating diode must be greater than the maximum line input voltage. Thermal Protection Internal Thermal Shutdown circuitry is provided to protect the integrated circuit in the event the maximum junction temperature is exceeded. When thermal protection is activated, typically at 165 degrees Celsius, the controller is forced into a low power reset state, disabling the output driver. This feature is provided to prevent catastrophic failures from accidental device overheating. Minimum Load Current A minimum load current of 1 mA is required to maintain proper operation. If the load current falls below that level, the bootstrap capacitor may discharge during the long off-time, and the circuit will either shutdown, or cycle on and off at a low frequency. If the load current is expected to drop below 1 mA in the application, the feedback resistors should be chosen low enough in value so they provide the minimum required current at nominal Vout.

Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
