上海芯龙一级代理:XL2576S-ADJE1/XL2576S-5.0E1/XL2576S-12E1 DC-DC异步降压3A 40V
日期:2020-4-7cellent line and load regulation. Requiring a minimum number of external components, the regulator is simple to use and include internal frequency compensation and a fixed-frequency oscillator. The PWM control circuit is able to adjust the duty ratio linearly from 0 to 100%. An enable function, an over current protection function is built inside. An internal compensation block is built in to minimize external component count.
