Product introduction

TPS40197 具有 4 位 VID 接口和电源状态良好指示的 4.5V 至 14V 输入同步降压控制器

illustrate

该TPS40197是一个同步降压控制器，工作于4.5 V至14 V的输入电源名义。该控制器实现了与520 kHz固定开关频率电压模式控制架构。 Higher switching frequencies facilitate smaller inductors and output capacitors, providing a compact power solution. An adaptive anti-crossover scheme is used to prevent current from being shot at the power FET.

该TPS40197集成了PWM控制在一个单一的芯片和4位VID接口，允许无缝上的实时转换率，可编程VID变化。它提供了一个智能反射™DSP内核简单的电源解决方案。

短路检测是通过检测完成整个低端FET的电压降时，就和比较用户选择它的门槛为100毫伏，200毫伏或280毫伏。
