High-voltage buck controller

PV88080提供一个PWM降压控制器和三个可调节的同步降压调节器。高压降压控制器可任选地用于为其他三个降压转换器产生电源。高压降压控制器的高侧和低侧的两个通路设备（NMOS FET）是外部的，允许大部分降压控制器功耗在PV88080之外。该高压降压控制器采用恒定的时间（COT）控制方案，具有集成的引导PMOS开关。

In certain applications, multiple PV88080s can be used together to provide enough power rails to power the larger systems. There are three buck converters that can be used to generate the supplies for CPUs, DDR memory and other Auxiliary functions in a typical application. The pass devices of these buck converters are fully integrated, so no external FETs or Schottky diodes are needed. This results in optimized power efficiency and a reduced external component count.
