Description
The PT6715 series of power modules
are a 13-A rated integrated switching
regulator (ISR), housed in a 17-pin space
saving solderable copper package. These
modules will operate off either a 5V or
3.3V input power bus to provide a high-
performance low-voltage power source for
the industry’s latest high-speed, DSPs,
µPs, and bus drivers. This allows for the
easy integration of these new low-voltage
ICs into existing 3.3V or 5V systems with-
out re-designing the central power supply.
The series includes the standard output
bus voltage options, ranging from 1.0V
to 3.3V. Each output voltage option has
a limited adjust range.
Features include a Standby (On/Off)
function, a differential output Remote
Sense, and short circuit protection. The
modules are available in both through-
hole and surface mount configurations.
