UD32121 Datasheet (UTC) - 1.4MHz STEP-DOWN CONVERTER

UD32121, 1.4MHz STEP-DOWN CONVERTER

The UTC UD32121 is a monolithic step-down switching mode converter with a built-in power MOSFET.

It regulates input voltages from 4.5V to 32V down to an output voltage as low as 0.81V, and supplies up to 1.2A of load current.

Current mode operation provides fast transient response and eases loop sta
