Features & Applications
The L5973D013TR is a step down monolithic power switching regulator with a minimum switch current limit of 2.5 A so it is able to deliver more than 2 A DC current to the load depending on the application conditions.
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.
Features:
- 2.5 A internal switch
- Operating input voltage from 4 V to 36 V
- 3.3 V / (±2%) reference voltage
- 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
- Inhibit for zero current consumption
- Synchronization
- 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
