Description
●The L5970D is a step down monolithic power switching regulator capable to deliver up to 1A at output voltages from 1.2V to 35V. The device uses an internal P-Channel D-MOS transistor (with a typical Rdson of 250mΩ) as switching element to minimize the size of the external components.
●General features
●■ Up to 1A output current
●■ Operating input voltage from 4.4V to 36V
●■ 3.3V / (±2%) reference voltage
●■ Output voltage adjustable from 1.2V to 35V
●■ Low dropout operation: 100% duty cycle
●■ 250KHz 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
