PT6510 Series
8-A 5-V/3.3-V Input Adjustable ISR with Short-Circuit protection
SLTS220 FEBRUARY 2004
Features
• 8-A Rated Output Current • Replaces PT6500 Series • High Efficiency (91% for PT6511) • Small Footprint (0.75 in², Suffix ‘N’) • Output On/Off Standby Control • Output Short-Circuit Protection • Over-Temperature Protection • Adjustable Output Voltage • Soft Startup • 16-pin Mount Option (Suffixes L & F)
Description
The PT6510 series of power modules is the recommended direct replacement for the PT6500 series in existing designs. The modules have the same output current rating as the PT6500 series (8 A) and were designed to be functionally identical in as many aspects as possible. This includes the input voltage range, on/off standby control, and output voltage adjustment.
When used as a replacement, a PT6510 series part exhibits a number of performance enhancements over its PT6500 series equivalent. These include improved power dissipation and efficiency, significantly reduced inrush current, and better line and load regulation.
The modules are housed in the same 14-Pin SIP (Single In-line Package), and include the same package options.

Notes: (1) The ISR will operate at no load with reduced specifications.
(2) The minimum input voltage required by the part is Vout + 1.2 V, or 3.1 V, whichever is greater. (3) The STBY* control (pin 3) 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, Vin. Refer to the application notes for other interface considerations. (4) The module requires a 3.
