This family of devices offers design flexibility with a variety of user programmable functions, including; soft-start, UVLO, operating frequency, voltage feedforward, high-side current limit, and loop compensation. These devices are also synchronizable to an external supply. The TPS40060 and TPS40061 incorporate MOSFET gate drivers for external P-channel high-side and Nchannel synchronous rectifier (SR) MOSFETs. Gate drive logic incorporates anti-cross conduction circuitry to prevent simultaneous high-side and synchronous rectifier conduction.
