UD24121 - 1.4MHz STEP-DOWN CONVERTER
The UTC UD24121 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 0.81V, and supplies up to 1.2A of load current.
Current mode operation provides fast transient response and eases loop sta
