P1785 Overview
Key Specifications
Mount Type: External
Description
UTC P1785 consists of 2A step-down switching regulator control which includes a reference voltage source, oscillation circuit, error amplifier, internal PMOS and etc with PWM. UTC P1785 can provide low-ripple power, high efficiency, and excellent transient characteristics and an enable function, an over current protect function and a short circuit protect function are built inside, so the operation frequency will be reduced from 300KHz to 30KHz when OCP or SCP happens.
