P1482

UNISONIC TECHNOLOGIES CO., LTD P1482 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. 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 * 2A Output Current * Wide 6V~18V 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 P1482L-S08-R P1482G-S08-R Package SOP-8 SOP-8 Packing Tape Reel  MARKING www.unisonic.com.tw Copyright © 2017 Unisonic Technologies Co., Ltd 1 of 5 QW-R103-057.K P1482  PIN CONFIGURATION LINEAR INTEGRATED CIRCUIT  PIN DESCRIPTION PIN NO. 1 2 3 4 5 6 7 8 PIN NAME NC VIN SW GND FB COMP EN SS No Bondin...
