Description
The PT5500 Excalibur鈩?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鈥檚 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 100碌F capacitor
is required for proper operation.
