UC2000D中文资料HIGH PRECISION LOW COST MCM POWER SWITCH数据手册UTC规格书

描述 Description

The UTC UC2000D  is a high performance, high precision and low cost PWM Power switch for non-isolated buck application. It combines a dedicated current mode PWM controller and error amplifier for low component count. UTC  UC2000D use UTC proprietary frequency shuffling technique for EMI performance. And oscillator with frequency-reduction control is implemented.   The UTC  UC2000D  has soft start control and protection function, such as Cycle-by-Cycle current limiting, Over Loading Protection, Output Short-Circuit Protection, RCS short Protection, OTP, VDD OVP, and UVLO.
