Features & Applications
The L5972D is a step down monolithic power switching regulator with a minimum switch current limit of 2 A so it is able to deliver more than 1.5 A DC current to the load depending on the application conditions.
The output voltage can be set from 1.235 V to 35 V. The device uses an internal P-Channel D-MOS transistor (with a typical Rdson of 250 mΩ) as switching element to minimize the size of the external components. An internal oscillator fixes the switching frequency at 250 kHz. Having a minimum input voltage of 4.4 V only, it is particularly suitable for 5V bus, available in all computer related applications.
Features:
- 2 A internal switch
- Operating input voltage from 4.4 V to 36 V
- Output voltage adjustable from 1.235 V to 35 V
- Low dropout operation: 100% duty cycle
- 250 kHz Internally fixed frequency
- Voltage feedforward
- Zero load current operation
- Internal current limiting
- Protection against feedback disconnection
- Thermal shutdown
Applications:
- Consumer: STB, DVD, TV, VCR, car radio, LCD monitors
- Networking: XDSL, modems, DC-DC modules
- Computer: printers, audio/graphic cards, optical storage, hard disk drive
- Industrial: changers, car battery, DC-DC converters
