P1482 Datasheet

RF 2A, 30V, 340KHZ SYNCHRONOUS RECTIFIED STEP-DOWN CONVERTER
 
 


DESCRIPTION
 
 
The UTC P1482 is a synchronous buck regulator. The device
provides 2A of continuous load current over a wide input voltage
of 6V~24V. Current mode control provides fast transient response
and cycle-bycycle current limit. An adjustable soft-start prevents
inrush current at turn-on  
The UTC P1482 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.
