Overview

UNISONIC TECHNOLOGIES CO.
, LTD UD18203 Preliminary LINEAR INTEGRATED CIRCUIT 2A, 18V SYNCHRONOUS FAST RESPONSE BUCK CONVERTER  DESCRIPTION The UTC UD18203 is a monolithic synchronous buck regulator with built-in main switch and synchronous switch power MOSFETs.
It operates over a wide input voltage range from 4.
5V to 18V and achieves 2A continuous output current.
It adopts PWM architecture to achieve fast transient response and high efficiency at light loads.
It operates at pseudo-constant frequency of 500kHz under heavy load conditions.
Internal soft-start minimizes the inrush supply current at initial startup.
 FEATURES * 4.
5V~18V Input Voltage Range * Up to 2A Output Current * 140...
