SIMPLIFIED APPLICATION
DESCRIPTIONThe 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. They incorporate 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.
The externally programmable current limit provides
pulse-by-pulse current limit, as well as hiccup mode
operation utilizing an internal fault counter for longer
duration overloads.
