Description

The PT6650 power modules are a series

of high efficiency, non-isolated step-down

integrated switching regulators (ISRs).

These regulators are designed to operate

over a 9 V to 28 V input voltage range to

produce a tightly regulated output voltage

at load currents of up to 5 A. The wide

input voltage range allows them to oper-

ate off either a 12 V or 24 V DC input

bus system, making them ideal for general

purpose and industrial applications. The

series includes standard output voltage

options ranging from 15 V down to 2.5 V,

and down to 1.8 V with adjustment. Only

two external capacitors are required for

proper operation.

The PT6650 series is housed in a low-

cost 14-pin SIP (Single In-line Package) and

is available in both vertical and horizontal

configurations, including surface-mount.
