3 Description
The TPS61175-Q1 is a monolithic switching regulator
with integrated 3-A, 40-V power switch. It can be
configured in several standard switching-regulator
topologies, including boost, SEPIC and flyback. The
device has a wide input voltage range to support
application with input voltage from multi-cell batteries
or regulated 5-V, 12-V power rails.
The TPS61175-Q1 regulates the output voltage with
current mode PWM (pulse width modulation) control.
The switching frequency of PWM is either set by an
external resistor or an external clock signal. The user
can program the switching frequency from 200-kHz to
2.2-MHz.
The
device
features
a
programmable
soft-start
function to limit inrush current during start-up, and
has built-in other protection features, such as pulse-
by-pulse over current limit and thermal shutdown. The
TPS61175-Q1
is
available
in
14-pin
HTSSOP
package with PowerPAD.
