Preliminary Datasheet

LP6470

600KHz, 16V/2A Synchronous Step-down Converter

General Description

The LP6470 contains an independent 600KHz

constant frequency, current mode, PWM step-down

converters. The converter integrates a main switch

and a synchronous rectifier for high efficiency

without an external Schottky diode. The LP6470 is

ideal for powering portable equipment that runs

from a 2cell Lithium-Ion (Li+) battery. The converter

can supply 2000mA of load current from a 3.5V to

16V input voltage. The output voltage can be

regulated as low as 0.8V.

The LP6470 is available in a SOT23-6 package and

is rated over the -40℃ to 85℃ temperature range.
