DESCRIPTION
The TPS40060 and TPS40061 are high-voltage, wide
input (10 V to 55 V) synchronous, step-down
converters.
This family of devices offers design flexibility with a
variety of user programmable functions, including;
soft-start, UVLO, operating frequency, voltage feed-
forward, 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.
