HIGH-EFFICIANCY MIDRANGE INPUT SYNCHRONOUS

BUCK CONTROLLER WITH VOLTAGE FEED-FORWARD

FEATURES

DESCRIPTION

•

Operation Over 4.5-V to 28-V Input Range

Programmable Fixed-Frequency up to 1-MHz

Voltage-Mode Controller

Predictive Gate Drive™ With Anti-Cross

Conduction Circuitry

<1% Internal 700-mV Reference

Internal Gate Drive Outputs for High-Side and

Synchronous N-Channel MOSFETs

16-Pin PowerPAD™ Package

Thermal Shutdown Protection

TPS40070: Source Only

TPS40071: Source/Sink

Programmable High-Side Sense Short Circuit

Protection

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 recti-

fier (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.
