    UNISONIC TECHNOLOGIES CO., LTD P1785 LINEAR INTEGRATED CIRCUIT PWM CONTROL 2A STEP-DOWN CONVERTER  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. And 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.
