(2) The Inhibit control (pin 1) has an internal pull-up and if it is left open circuit the module will operate when input power is applied. The open-circuit voltage is the input voltage V in. Use a discrete MOSFET to control the Inhibit pin, and ensure a transitioin time of less than ≤ 10µs. Consult the related application note for other interface considerations. (3) For operation below 0°C, Cin and Cout must have stable characteristics. Use either low ESR tantalum or Oscon® capacitors. (4) See Safe Operating Area curves or contact the factory for the appropriate derating. (5) The case pins on through-hole package types (suffixes N & A) must be soldered. For more information consult the applicable package outline drawing. Input/Output Capacitors: The PT6340 regulator series requires a 100µF electrolytic (or tantalum) capacitor at the input and 330µF at the output for proper operation in all applications. In addition, the input capacitance, C in, must be rated for a minimum of 740mArms of ripple current, and the ESR of the output capacitor, Cout , must less than 50m Ω @100kHz. For transient or dynamic load applications additional output capacitance may be necessary. For more information consult the related application note on capacitor recommendations.

These devices incorporate an inhibit function, which may be used in applications that require a power-up/shutdown feature. The inhibit function is provided by the Inhibit* control, pin 1. If pin 1 is left open-circuit the regulator operates normally, and provides a regulated output whenever a valid supply voltage is applied to Vin (pins 2– 4) with respect to GND (pins 5–8). If a low voltage 2 is then applied to pin 1 the regulator output will be disabled and the input current drawn by the ISR will typically drop to 0.5mA 4. The standby control may also be used to hold-off the regulator output during the period that input power is applied. The Inhibit* input can be controlled with an open-collector (or open-drain) discrete transistor (See Figure 1). The input is internally pulled-up to the input voltage, Vin 1. Table 1 gives the control voltage requirements. Table 1 Inhibit Control Requirements 3 Parameter Min Typ VIL VIH IIL -0.1V 2.0V Max 0.6V Vin 0.5mA Notes: 1. The inhibit control input requires no external pull-up resistor. The open-circuit voltage of the Inhibit* input is typically the input voltage, Vin.

Correspondingly, turning Q1 off removes the low-voltage signal and enables the output. Once enabled, the output will typically experience a 10–15ms delay followed by a predictable ramp-up of voltage. The regulator should provide a fully regulated output voltage within 30ms. The waveform of Figure 2 shows the output voltage response of a PT6342 (3.3V) following the turn-off of Q1. The turn off of Q1 corresponds to the rise in Vinh. The waveforms were measured with a 12Vdc input voltage, and 2 ½ Adc load. Figure 2 2. The inhibit control input is Not compatible with TTL devices. An open-collector device, preferably a discrete bipolar transistor (or MOSFET) is recommended. To ensure the regulator output is disabled, the control pin must be pulled to less than 0.6Vdc with a low-level 0.5mA sink to ground. Vo (2V/Div) Iin (0.5A/Div) 3. An external source voltage can be used to control the Inhibit* pin. To guarantee the inhibit and enable status of the regulator, the source must be capable of meeting the voltage requirements in Table 1 . 4. When the regulator output is disabled the current drawn from the input source is typically reduced to 0.5mA.

The ripple current rating, ESR, and operating temperature are the major considerations when selecting the input capacitor. It is recommended that tantalum capacitors have a minimum voltage rating of twice (2×) the maximum dc voltage, plus the ac ripple. This is necessary to insure reliability with 12V input voltage bus applications. None of the 100µF tantalum capacitors were found to meet this requirement. Input Capacitors: Output Current >4A Continuous (Table 2) The recommended input capacitance is determined by 1.0 amperes (rms) minimum ripple current rating and 100µF minimum capacitance. The ripple current rating, combined with less than 100mΩ ESR (equivalent series resistance) value are the major considerations, along with temperature, when selecting the input capacitor. It is recommended that tantalum capacitors have a minimum voltage rating of twice (2×) the maximum dc voltage, plus the ac ripple. This is necessary to insure reliability for 12V input voltage bus applications. None of the 100µF tantalum capacitors were found to meet this requirement. Output Capacitors: Output Current 0–6A (Table 1 & Table 2) The ESR of the required capacitor must be less than, or equal to 50mΩ. Electrolytic capacitors have poor ripple performance at frequencies greater than 400kHz but excellent low frequency transient response. Above the ripple frequency, ceramic decoupling capacitors are necessary to improve the transient response and reduce any high frequency noise components apparent during higher current excursions. Preferred low ESR type capacitor’s part numbers are identified in the capacitor tables. For technical support and more information, see inside back cover or visit www.ti.com Tantalum Capacitors Tantalums are acceptable on the output bus but only the AVX TPS series, Sprague 593D/594/595 series or Kemet T495/T510 series. These capacitors are recommended over many other types due to their higher rated surge, power dissipation, and ripple current capability. As a caution, the TAJ series by AVX is not recommended. This series exhibits considerably higher ESR and lower ripple current capability. The TAJ series is also less reliable than the TPS series when determining power dissipation capability. Tantalum or Oscon capacitor types are recommended for applications where ambient temperatures fall below 0°C. Capacitor Tables Table 1 and Table 2 identify the vendors with acceptable ESR and maximum allowable ripple current (rms) ratings. The output capacitors are identified in both tables under the “Output Bus” column with the required quantity. The input capacitors are listed in both tables. Table 1 has the recommended input capacitors when operating the ISR at a load current of 4Adc or less, and Table 2 identifies input capacitors for ISR load currents greater than 4Adc. This is not an extensive capacitor list. Capacitors from other vendors are available with comparable specifications. Those listed are for guidance. The RMS ripple current rating and ESR (Equivalent Series Resistance at 100kHz) are critical parameters necessary to insure both optimum regulator performance and long capacitor life.

TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
