NCP1510 Advance Information PWM Buck Converter with a Very Low Iq During Low Load Conditions The NCP1510 is a tri−mode regulator that operates either as a Synchronized PWM Buck Converter, PWM Buck Converter with internal oscillator or as a Pulsed Switching Regulator. If a synchronization signal is present, the NCP1510 operates as a current mode PWM converter with synchronous rectification. The optional external frequency input signal allows the user to control the location of the spurious frequency noise generated by a PWM converter. The Pulsed Switching Regulator mode is active when the Sync Pin is Low. The Pulsed Mode is an extremely low quiescent current Buck Converter. NCP1510 operates in a PWM mode with an internal oscillator when the Sync Pin is held high. The NCP1510 configuration allows the flexibility of efficient high power operation and low input current during system sleep modes. http://onsemi.com MARKING DIAGRAM 1 • Synchronous Rectification for Higher Efficiency in PWM Mode • Pulsed Switching Mode Operation for Low Current Consumption at • • • • • • • • • • • 1 DAK = Device Code YY = Year WW = Work Week Features Low Loads Output Current of 300 mA in PWM and 30 mA in Pulse Mode Integrated MOSFETs and Feedback Circuits Cycle−by−Cycle Current Limit Automatic Switching Between PWM, with External or Internal Oscillator, and Pulsed Mode Operating Frequency Range of 450 to 1000 kHz Internal 1.0 MHz Oscillator Thermal Limit Protection Built−in Slope Compensation for Current Mode PWM Converter 1.05, 1.35, 1.57, 1.8 Fixed Output Voltages Shutdown Current Consumption of 0.2 A Pb−Free Package for Green Manufacturing DAK YYWW 9 PIN MICRO BUMP FC SUFFIX CASE 499AC PIN CONNECTIONS A1 B1 C1 A2 B2 C2 A3 B3 C3 Pin: A1. − GNDP A2. − LX A3. − VCC B1. − SYNC B2. − GNDA B3. − FB C1. − SHD C2. − CB1 C3. − CB0 (Bottom View) ORDERING INFORMATION Device Package Shipping Applications • • • • • NCP1510FCT1G 9 Pin Pb−Free 3000 Tape & Reel Micro Bump Cellular Phones and Pagers PDA Digital Cameras Supplies for DSP Cores Portable Applications G Suffix parts indicate a Pb−Free package and requires use with a Pb−Free assembly process. †For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specifications Brochure, BRD8011/D.

Its unique features provide an efficient power supply for a portable device at full operating current, while also providing extremely low standby current for idle mode operation. When the system is idle, the user can activate the pulsed mode function. In this mode, the regulator provides a regulated low current output voltage keeping the system biased. When the device is in its normal operating mode, the regulator synchronizes to the system clock or uses an internal 1.0 MHz clock and turns into a switching regulator. This allows the regulator to provide efficient power to the system. This circuit is patent pending. Table 1. Sync Pin Input with Corresponding Operational Mode of NCP1510 Sync Pin State Operational Mode Low Low Iq Pulsed Mode Operation High PWM Using Internal Oscillator for the Clock Clock PWM Using Rising Edge of Clock Signal to Turn On PFET Pass Element PWM Mode with External Synchronization Signal During normal operation, a synchronization pulse acts as the clock for the DC/DC controller. The rising edge of the clock pulls the gate of Q1 low allowing the inductor to charge. When the current through Q1 reaches either the current limit or feedback voltage reaches its limit, Q1 will turn off and Q2 will turn on. Q2 replaces the free wheeling diode typically associated with Buck Converters. Q2 will turn off when either a rising edge sync pulse is present or all the stored energy is depleted from the inductor. The output voltage accuracy in the PWM mode is well within 3% of the nominal set value. An overvoltage protection circuit is present in the PWM mode to limit the positive voltage spike due to fast load transient conditions. If the OVP comparator is activated, the duty cycle will be 0% until the output voltage falls to the nominal level. The PWM also has the ability to go to 100% duty cycle for transient conditions and low input to output voltage differentials. In PWM mode operates as a forced−PWM converter. Each switching cycle has a typical on−time of 75nsec. NCP1510 has two protection circuits that can eliminate the minimum on time for the cycle. When tripped, the overvoltage protection or the thermal shutdown overrides the gate drive of the high side MOSFET. Operation Description The Buck regulator is a synchronous rectifier PWM regulator with integrated MOSFETs. This regulator has a Pulsed function for low power modes to conserve power. The Tri PWM with external or internal oscillator/pulsed mode is an exclusive Patent Pending circuit. For the PWM Synchronization mode, the operating frequency range for the NCP1510 is 450 to 1000 kHz. The output current of the PWM is optimized for 100 mA with a maximum current supply of over 300 mA for the 2.5 to 5.2 input voltage range. If the Sync Pin is held low, the NCP1510 changes into the Pulsed mode. The Pulsed function assures the user of an extremely low input current and greatly reduced quiescent current when the users system is in a sleep mode. Internally to the NCP1510, the Synchronization pin has a pull down resistor to force the part into Pulsed mode when a clock signal is not present. The Pulsed mode guarantees an output of 30 mA. If the Sync Pin is held high, NCP1510 enters a PWM mode with an internal 1.0 MHz oscillator. The PWM mode has the same operational characteristics (current limit, maximum output current, etc.) as the synchronized PWM mode. The Sync Pin threshold is fixed as noted in the Electrical Characteristics table. http://onsemi.com 6 NCP1510 L1 Q1 LOAD 6.8 H Sync C1 10 Vbat Set En Ramp IQ1 R1 OC Detect + R2 R3 Latch S Q R En COMP C2 10 − − + + Vref+5% − Q2 Error Amp OVP COMP R4 Vref Figure 3.

Waveforms During PWM Operation PWM Mode with Internal Oscillator Pulsed Mode If a synchronization signal is not available, the converter has a 1.0 MHz internal oscillator available. The Sync Pin must be held high to enter this mode. The characteristics of the PWM mode with internal oscillator are similar to the Sync PWM Mode. During low−level current output, NCP1510 can enter a low current consumption mode when the Sync Pin is held low. This mode will typically have a free running frequency and an output voltage ripple similar to a PFM mode. The advantage of the Pulsed mode is much lower Iq (14 A) and drastically higher efficiency compared with PWM and PFM modes in low output loads. http://onsemi.com 7 NCP1510 1200 100 90 1000 Pulse 80 EFFICIENCY (%) Iin (A) 800 PFM Mode 600 400 Pulsed Mode 70 60 50 40 30 PWM VCC = 3.6 V Freq PWM = 1.0 MHz TA = 25°C 20 200 10 0 0 200 400 600 Iout (A) 800 0 0.01 1000 10 100 1000 Figure 6.

When activated, typically at 160°C, the PWM latch is reset and the linear regulator control circuitry is disabled. The thermal shutdown circuit is designed with 25°C of hysteresis. This means that the PWM latch and the regulator control circuitry cannot be re–enabled until the die temperature drops by this amount. This feature is provided to prevent catastrophic failures from accidental device overheating. It is not intended as a substitute for proper heat−sinking. The NCP1510 is contained in a 9 pin micro bump package. The CB1 and CB0 pins control the output voltage selection. The output voltages are listed in Table 2. The CB pins contain internal resistors to force the NCP1510 to 1.35 Vout if they are not connected to an external circuit. The CB0 has a pull down resistor and the CB1 has a pull up resistor. The CB Pin thresholds are fixed as noted in the Electrical Characteristics table. Shutdown Pin The Shutdown Pin enables the operation of the device. The Shutdown Pin has an internal pull down resistor to force the NCP1510 into the off mode if this pin is floating due to the external circuit. The Shutdown Pin threshold is fixed as noted in the Electrical Characteristics table. During Start−up, the NCP1510 has a soft start function to limit fast dV/dt and eliminate overshoot on the output.
