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.
