LINEAR INTEGRATED CIRCUIT
2A, 18V, 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~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 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....
