DESCRIPTION

1%, 690-mV Reference

The TPS40101 is

wide-input synchronous,

Output Margining, 3% and 5%

Programmable UVLO and Hysteresis

Frequency Synchronization

step-down controller that offers programmable closed

loop soft-start, programmable UVLO and hysteresis,

programmable current limit with hiccup recovery and

can be synchronized to other timebases. The

TPS40101 incorporates MOSFET gate drivers for

external N-channel MOSFETs. Gate drive logic

incorporates adaptive anti-cross conduction circuitry

for improved efficiency, reducing diode conduction in

the rectifier MOSFET.
