PWM Control 3A Step-down Converter

PWM control 3A Step-down converter P1786 UTC P1786 consists of 3A Step-down Switching Regulator control which include a reference voltage source, oscillation circuit, error Amplifier internal PMOS and etc with PWM. UTC P1786 CAN provide low-ripple power, high efficiency, and excellent transient characteristics. An enable function, an over current protect and short circuit protect function are built inside, so the operation frequency CAN be reduced from 300KHz to 30KHz when OCP or SCP happens. The PWM control circuit CAN vary the duty ratio linearly from 100 down to 0%. This converter also includes an error Amplifier circuit as well as a soft-start circuit that prevents overshoot at startup. Also, to minimum external component counts for an internal compensation block is built in. By LianShun Electronics Co., Ltd
