The L5972D is a step down monolithic Power Switching Regulator with a minimum switch current limit of 2A so it is able to deliver more than 1.5A DC current to the load depending on the application conditions. The device uses an internal P-channel D-MOS transistor (with a typical RDS (ON) of 250mR) as switching element to minimize the size of the external components. Pulse-by-pulse current limit with the internal frequency modulation offers an effective constant current short circuit protection.
● Voltage feed-forward
● Zero load current operation
● Internal current limiting
● Protection against feedback disconnection
● Thermal shutdown
