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.
