Description

General part information

LT1612 Series

The LT1612 is an 800kHz, synchronous step-down DC/DC converter that operates from an input voltage as low as 2V. Internal 0.45Ohms switches deliver output currents up to 500mA, and the 800kHz switching frequency allows the use of small, low value ceramic input and output capacitors. Input voltage ranges from 5.5V down to 2V and output voltage can be set as low as the 620mV reference. The device features Burst Mode operation, keeping efficiency high at light loads. Burst Mode operation can be defeated by pulling the MODE pin high, enabling constant switching throughout the load range for low noise.No-load quiescent current is 160µA and shutdown current is less than 1µA. The device is available in 8-lead SO and MSOP packages.ApplicationsPortable DevicesLithium-Ion Step-Down Converters5V to 3.3V Conversion2-Cell Alkaline Step-Down Converters
