2A, 17V SYNCHRONOUS FAST RESPONSE BUCK CONVERTER

DESCRIPTION

The UTC UD18209 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 17V and achieves 2A continuous output current.
It adopts PWM architecture to achieve fast transient response
and always operates under continuous condition mode. It
operates at pseudo-constant frequency of 580kHz under heavy
load conditions. Internal soft-start minimizes the inrush supply
current at initial startup.
