Product Overview
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 250mΩ) 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
Applications
Consumer Electronics, Communications & Networking, Computers & Computer Peripherals, Industrial
