SYNCHRONOUS RECTIFIED

STEP-DOWN CONVERTER

DESCRIPTION

The UTC P1482A is a synchronous buck regulator. The

device provides 2A of continuous load current over a wide input

voltage of 6V~18V. Current mode control provides fast transient

response and cycle-bycycle current limit. An adjustable soft-start

prevents inrush current at turn-on.

The UTC P1482A can provide low-ripple power, high

efficiency, and perfect transient characteristics. The duty ratio

varies linearly from 0% to 92% in the PWM control. The error

amplifier circuit and soft-start circuit included in this device can

prevent overshoot at startup. An enable function, an over current

protect (OCP) function and short circuit protect (SCP) are also

build inside, and when OCP happens, the operation frequency

will be reduced.
