P1482A

UNISONIC TECHNOLOGIES CO., LTD P1482A 2A, 18V, 365KHZ SYNCHRONOUS RECTIFIED STEP-DOWN CONVERTER LINEARINTEGRATED CIRCUIT  DESCRIPTION The UTC P1482A 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 P1482A 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 365KHz Frequency * Cycle-by-Cycle Over Current Protection  ORDERING INFORMATION Ordering Number Lead Free Halogen Free P1482AL-SH2-R P1482AG-SH2-R Package HSOP-8 HSOP-8 Packing Tape Reel P1482AG-SH2-R (1)Packing Type (2)Package Type (3)Green Package  MARKING 876 5 UTC P1482A 1234 Date Code L: Lead Free G: Halogen Free Lot Code (1) R: Tape Reel (2) SH2: HSOP-8 (3) G: Halogen Free and Lead Free, L: Lead Free www.unisonic.c...
