Wide Input Synchronous Buck Controller With Voltage Feed Forward

The TPS40075 is a mid voltage, wide input (4.5-V to 28-V),synchronous, Step-down controller, offering design flexibility for a variety of user programmable functions, including; soft start, UVLO, operating frequency, voltage feed-forward and high-side FET sensed short Circuit Protection
The TPS40075 drives external N-Channel MOSFETs using second generation Predictive Gate Drive to minimize conduction in the body Diode of the low side FET and maximize efficiency. Pre-biased outputs are supported by not allowing the low side FET to turn on until the voltage commanded by the closed loop soft start is greater than the pre-bias voltage. Voltage feed forward provides good response to input transients and provides a constant PWM gain over a wide input voltage operating range to ease compensation requirements. Programmable short Circuit Protection provides fault current limiting and hiccup recovery to minimize power dissipation with a shorted output. The 20-pin QFN package gives good thermal performance and a compact footprint.
