TPS40057-Q1 描述

The TPS4005x is a family of high-voltage, wide input (8 V to 40 V), synchronous, step-down converters. The TPS4005x family 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.

The TPS4005x are also synchronizable to an external supply. The TPS4005x incorporates MOSFET gate drivers for external N-channel high-side and synchronous rectifier (SR) MOSFETs. Gate drive logic incorporates anti-cross conduction circuitry to prevent simultaneous high-side and synchronous rectifier conduction.

The TPS4005x uses voltage feed-forward control techniques to provide good line regulation over the wide (4:1) input voltage range and fast response to input line transients with near constant gain with input variation which eases loop compensation.
