The TPS40100 is a mid voltage, wide-input (between 4.5 V and 18 V), synchronous, step-down controller. The TPS40100 offers programmable closed loop soft-start, programmable UVLO (with programmable hysteresis), programmable inductor sensed current limit and can be synchronized to other timebases. The TPS40100 incorporates MOSFET gate drivers for external N-channel high-side and synchronous rectifier (SR) MOSFET. Gate drive logic incorporates adaptive anti-cross conduction circuitry for improved efficiency, reducing both cross conduction and diode conduction in the rectifier MOSFET. The externally programmable current limit provides a hiccup overcurrent recovery characteristic.
