TPS40101

MIDRANGE输入同步降压与高级排序和输出裕度控制器 MIDRANGE INPUT SYNCHRONOUS BUCK CONTROLLER WITH ADVANCED SEQUENCING AND OUTPUT MARGINING

The is a wide-input synchronous, 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.
