Unisonic Technologies UD24121
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. The UTC UD24121 requires a minimum number of readily available standard external components.DESCRIPTION
The UTC Current mode operation provides fast transient response and eases loop stabilization. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown.●
