Description

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
