(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 PT6440 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 350mArms of ripple current, and the ESR of the output capacitor, Cout, must less than 100m 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 Application Notes Capacitor Recommendations for the PT6440 Excalibur™ 5V/3.3V Bus Step-Down ISRs Input Capacitors The recommended input capacitance is determined by 350 milli-amperes (rms) minimum ripple current rating and 100µF minimum capacitance. Capacitors placed at the input must be rated for a minimum of twice the input voltage with +5V operation. Ripple current and ≤200mΩ Equivalent Series Resistance (ESR) values are the major considerations, along with temperature, when selecting the proper input capacitor. Output Capacitors The ESR of the required 330µF output capacitor must be less than or equal to 100m Ω . Failure to observe this requirement may lead to regulator instability or oscillation. Electrolytic capacitors have poor ripple performance at frequencies greater than 300kHz but excellent low fre- quency 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. The preferred low ESR type capacitor part numbers are identified in Table 1. Tanatalum Capacitors Tantalum capacitors are recommended on the output bus but only the AVX TPS series, Sprague 593D/594/595 series or Kemet T495/T510 series. These capacitors are specified over many other types due to their higher surge current, 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® types are recommended in applications where ambient temperatures fall below 0°C. Capacitor Table Table 1 identifies vendors with acceptable ESR and maximum allowable ripple current (rms) ratings. The suggested minimum quantities per regulator for both the input and output buses are identified. 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 perfor- mance and long capacitor life.
