DESCRIPTION
The TPS4007x is a mid voltage, wide input (4.5 V to
28 V), synchronous, step-down converter.
The TPS4007x offers design flexibility with a variety
of user programmable functions, including; soft-start,
UVLO, operating frequency, voltage feed-forward and
high-side FET sensed short circuit protection.
The TPS4007x incorporates MOSFET gate drivers for
external N-channel high-side and synchronous rectifier (SR) MOSFETs. Gate drive logic incorporates
predictive anti-cross conduction circuitry to prevent
simultaneous high-side and synchronous rectifier
conduction, while minimizing to eliminating current
flow in the body diode of the SR FET. The TPS40071
allows the supply output to sink current at all times.
The TPS40070 implements a source-only power
supply.
