PT6520 Series
8-A 5-V/3.3-V Input Adjustable ISR with Short-Circuit protection
SLTS104A
(Revised 1/25/2002)
Features
8A Rated Output Current Single Device: 3.3V/5V Input High Efficiency (92% for PT6521) Small Footprint (0.75 in², Suffix ‘P’) Output On/Off Standby Control Output Short-Circuit Protection Adjustable Output
Voltage Soft Startup 16-pin Mount Option
(Suffixes L, M, Q, & F)
Description These power modules are a series of
high performance, 8-A rated, Integrated Switching Regulators (ISRs), housed in a low cost 14-Pin SIP (Single In-line Package). Operating from either a 3.3V or 5V standard power bus, the PT6520 series produces a high-output, low-
voltage power source for the industry’s latest high-speed, microprocessors, ASICs, & DSPs. This allows for the easy integration of these new low-
voltage ICs into existing 3.3V or 5V systems without re-designing the power supply.
The PT6520 series features an output On/Off standby pin and output shortcircuit protection.
