UNISONIC TECHNOLOGIES CO., LTD P1484A LINEAR INTEGRATED CIRCUIT 3A, 18V, 365KHZ SYNCHRONOUS RECTIFIED STEP-DOWN CONVERTER  DESCRIPTION The UTC P1484A is a synchronous buck regulator. The device provides 3A of continuous load current over a wide input voltage of 5V~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 P1484A 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.
