3A, 23V, 340KHZ SYNCHRONOUS RECTIFIED STEP-DOWN CONVERTER
DESCRIPTION SOP-8
LINEAR INTEGRATED CIRCUIT
The UTC P1484 is a synchronous buck regulator.
The device provides3A of continuous load current over a wide input
voltage of 5V~23V.
Current mode control provides fast transient response and cycle-bycycle current limit.
An adjustable soft-start prevents inrush current at turn-on The UTC P1484 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.
