P4596
Preliminary
LINEAR INTEGRATED CIRCUIT
PWM CONTROL 3A STEP-DOWN CONVERTER
DESCRIPTION
The UTC P4596 consists of 3A step-down switching regulator with PWM control which includes a reference voltage source, oscillation circuit, error amplifier, internal PMOS and etc.
The UTC P4596 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, 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.
