2A, 24V, 1.4MHz STEP-DOWN

CONVERTER



DESCRIPTION

The UTC UD24202 is a monolithic step-down switching mode

converter with a built-in power MOSFET. It regulates input voltages

from 4.5V to 24V down to an output voltage as low as 0.83V, and

supplies up to 2A of load current.

Current mode operation provides fast transient response and

eases

loop stabilization. Fault condition protection includes

cycle-by-cycle current limiting and thermal shutdown.

The UTC UD24202 requires a minimum number of readily

available standard external components.


