SLVS892A –DECEMBER 2008–REVISED OCTOBER 2010

3-A High Voltage Boost Converter with Soft-start and Programmable Switching Frequency

Check for Samples: TPS61175

FEATURES

DESCRIPTION

•

2.9-V to 18-V Input Voltage Range

•

3A, 40V Internal Switch

The TPS61175 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.

High Efficiency Power Conversion: Up to 93%

Frequency Set by External Resistor: 200-kHz

to 2.2-MHz

•

Synchronous External Switching Frequency

User Defined Soft Start into Full Load

The TPS61175 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.

Skip-Switching Cycle for Output Regulation at

Light Load

•

14-pin HTSSOP Package with PowerPad™

APPLICATIONS

•

5V to 12V, 24V power conversion

Supports SEPIC, Flyback topology

ADSL Modems

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 is available in 14-pin

HTSSOP package with Powerpad.
