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

* 140/130mΩ Internal Power MOSFET Switch

* PWM Architecture to Achieve Fast Transient Response

* Build-in soft start function

* 500kHz Switching Frequency

* Thermal Shutdown Protection
