(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 p ackage 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 pro per 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.

For technical support and more information, see inside back cover or visit www.ti.com Capacitor Recommendations for the PT6340 6A Excalibur™ Regulator Series Input Capacitors: Output Current ≤≤≤≤≤4A Continuous (Table 1) The recommended input capacitance is determined by 740 milli-amperes (rms) minimum ripple current rating, less than 100m Ω ESR (equivalent series resistance), and 100µF mini mum capacitance. 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 100m Ω 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 50m Ω. 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 ex cursions. Preferred low ESR type capacitor’s part numbers are identified in the capacitor tables. PT6340 Series 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 recom- mended 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 identi- fies 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.
