P1484A

UNISONIC TECHNOLOGIES CO., LTD P1484A 3A, 23V, 340KHZ SYNCHRONOUS RECTIFIED STEP-DOWN CONVERTER „ DESCRIPTION HSOP-8 LINEAR INTEGRATED CIRCUIT The UTC P1484A 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 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. 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. „ FEATURES * 3A Output Current * Wide 6V~23V Operating Input Range * Integrated Power MOSFET Switches * Programmable Soft-Start * Stable with Low ESR Ceramic Output Capacitors * Fixed 340KHz Frequency * Cycle-by-Cycle Over Current Protection „ ORDERING INFORMATION Ordering Number Lead Free Halogen Free P1484AL-HS2-R P1484AG-HS2-R P1484AL-HS2-T P1484AG-HS2-T Package HSOP-8 HSOP-8 Packing Tape Reel Tube www.unisonic.com.tw Copyright © 2013 Unisonic Technologies Co., Ltd 1 of 6 QW-R103-063.A Free Datasheet http://www.Datasheet4U.com P1484A „ PIN CONFIGURATION LINEAR INTEGRATED CIRCUIT „ PIN DESCRIPTION PI...
