Texas Instruments TPS40075RHLR

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.

是的tps40075中压、宽输入(4.5-v至28),同步降压控制器,用于各种用户可编程功能,包括提供设计的灵活性;软启动、欠压锁定,操作频率、电压前馈和高侧FET检测短路保护。
的tps40075驱动外部N沟道MOSFET栅极驱动采用第二代预测最小的低侧FET的体二极管导通,实现效率最大化。预偏置输出通过不允许低侧FET打开,直到闭环软启动所指示的电压大于预偏置电压。电压前馈提供了良好的响应输入瞬变,并提供一个恒定的PWM增益在宽输入电压工作范围,以减轻补偿要求。可编程短路保护提供故障电流限制和打嗝恢复,以尽量减少功耗与短路输出。20引脚QFN封装提供了良好的热性能和紧凑的足迹。
