PT5500 Series
3-A 5-V/3.3-V Input Adjustable Integrated Switching Regulator
SLTS132A
(Revised 10/5/2001)
Features
· · · · · · · · · Single-Device: 5V/3.3V Input DSP Compatible 90% Efficiency Small Footprint Space-Saving package Adjustable Output Voltage Output Inhibit Function Short Circuit Protection Solderable Copper Case
Description
The PT5500 ExcaliburTM power modules are a series of high-performance Integrated Switching Regulators (ISRs). Rated 3A, these modules operate from input voltages as low as 3.1V to provide a local step-down power source. They are an ideal compliment to the industry's latest high-performance DSPs and microprocessors. The series includes output voltage options as low as 1.0VDC. The PT5500 series is packaged in a 5-pin thermally efficient copper case. The case is solderable, has a small footprint, and can accommodate both through-hole and surface mount pin configurations. The product features external output voltage adjustment, an inhibit function, and short circuit protection. A 100µF capacitor is required for proper operation.

Notes: (1) The ISR will operate down to no load with reduced specifications. (2) This is a typical value only. The switching frequency will vary with input voltage. (3) The Inhibit control (pin 1) has an internal pull-up, and if left open-circuit the module will operate when input power is applied. A small low-leakage (<100nA) MOSFET is recommended to control this input. Ensure an On/Off transition time of 10µs. See application notes for more information. (4) The PT5500 Series requires a 100µF electrolytic or tantalum output capacitor for proper operation in all applications. (5) For operation below 0°C, the output capacitor C2 must have stable characteristics. Use either a low ESR tantalum or Oscon® capacitor. (6) See SOA curves or consult factory for the appropriate derating. (7) The case pins on the through-hole package types (suffixes N & A) must be soldered. For more information see the applicable package outline drawing.
