MIDRANGE INPUT SYNCHRONOUS BUCK CONTROLLER WITH VOLTAGE FEED-FORWARD
TPS40074 www.ti.com SLUS617B–APRIL 2005–REVISED OCTOBER 2006 MIDRANGE INPUT SYNCHRONOUS BUCK CONTROLLER WITH VOLTAGE FEED-FORWARD The TPS40074 uses voltage feed-forward control FEATURES techniques to provide good line regulation over a • Operation Over 4.5-V to 28-V Input Range wide input voltage range, and fast response to input • Fixed-Frequency Voltage-Mode Controller line transients. Voltage feed-forward also provides • Integrated Unity Gain Amplifier for Remote nearly constant power stage gain with input variation to ease loop compensation of wide input range Output Sensing designs. The externally programmable short circuit • Predictive Gate Drive™ Generation II for protection provides fault current limiting, as well as Improved Efficiency hiccup mode operation for low power dissipation in • <1% Internal 700-mV Reference the presence of a shorted output. The TPS40074 is packaged in a 20-pin QFN package for better • Input Voltage Feed Forward Control thermal performance at higher voltages and • Prebiased Output Compatible frequencies, as well as reduced footprint. • Internal Gate Drive Outputs for High-Side and Synchronous N-Channel MOSFETs SIMPLIFIED APPLICATION DIAGRAM • Switching Frequency Programmable to 1 MHz V + V − OUT OUT (at Load) (at Load) • 20-Pin QFN Package • Thermal Shutdown Protection 1 20 • Software Design Tool and EVM Available SA− SA+ TPS40074 SYNC IN APPLICATIONS 2 SAO SYNC 19 PowerGood OUT • Power Modules 3 GND PGD 18 • Networking/Telecom 4 SS LVBP 17 • Industrial • Servers 5 FB RT 16 6 COMP KFF 15 DESCRIPTION 7 PGND ILIM 14 The TPS40074 is a mid voltage, wide input (4.5-V to V IN 28-V), synchronous, step-down controller, offering 8 LDRV VDD 13 design flexibility for a variety of user programmable functions, including; soft start, UVLO, operating 9 DBP HDRV 12 frequency, voltage feed-forward and high-side FET sensed short circuit protection. SW BOOST 10 11 The TPS40074 incorporates MOSFET gate drivers for external N-channel high side and synchronous rectifier (SR) MOSFETs. The gate drive logic incorporates second generation predictive anti-cross conduction circuitry to prevent simultaneous high side and synchronous rectifier conduction, while minimizing to eliminating current flow in the body V − V + OUT OUT diode of the SR FET. The TPS40074 allows for UDG−04075 starting into pre-biased outputs by not allowing the synchronous rectifier FET to turn on until the commanded voltage during soft start is greater than the existing pre-bias voltage.
