 DESCRIPTION

UD36241 is a high-efficiency, monolithic asynchronous

stepdown DC/DC converter that can deliver up to 2.4A output

current from a 9V to 36V input supply. The UD36241’s current

mode architecture with internal compensation is optimized for 5V

car charger application over a wide range of loads and output

capacitors. Cycle-by-cycle current limit provides protection against

shorted outputs and soft-start eliminates input current surge during

start-up. The UD36241 also provides output over voltage protection

output under voltage protection and thermal shutdown protection.

The low current (<10mA) shutdown mode provides output

disconnect, enabling easy power management in battery-powered

systems.
