高频率升压转换器，功率MOSFET输出26V软启动回路补偿

一.产品概述

CXSU63125 CXSU63125D 是一款高频率的升压转换器，内部集成了3A 0.1Ω的功率MOSFET，大输出可以到26V，1.2MHZ的工作频率减小了输入输出电容、电感选择和纹波。还集成了软启动、回路补偿，外围只需很少的器件。它的开关电流门限可以通过一个电阻或模拟电压（MCU I/O）简单设定。

The CXSU63125 CXSU63125D is a high frequency, high efficiency DC to DC converter with an integrated 3A, 0.1Ω power switch capable of providing an output voltage up to 26V. The fixed 1.2MHz allows the use of small external inductions and capacitors and provides fast transient response. It integrates Soft start, Comp,. only need few components outside. It can be adjusted SW current limit by one resistor or one analog voltage.
