TPS40075

illustrate

TPS40060 synchronous step-down converters with TPS40061 high voltage, wide input (10 V to 55 V).

The devices are designed to provide user-programmable features including flexible, soft-start, undervoltage lockout, operating frequency, voltage feedforward, high-side current limiting, and loop compensation. These devices can also be synchronized to an external power source.

TPS40060 gate driver of the MOSFET that integrates the external P-channel high-side and N-channel synchronous rectification (SR) MOSFETs with TPS40061. A drive logic gate reverse circuit is used to prevent cross-conduction, synchronous high-side, and synchronous rectifier conduction.
