UC2000D Overview
The UTC UC2000D is a high performance, high precision and low cost PWM Power switch for non-isolated buck application. It bines a dedicated current mode PWM controller and error amplifier for low ponent count. UTC UC2000D use UTC proprietary frequency shuffling technique for EMI performance.
