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 Pack-

age). 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 short-

circuit protection.
