1.5MHz,

1.5A Step-down Converter With Soft-Start

General Description

The LP6302 contains two independent 1.5MHz 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 LP6302 is ideal for

powering portable equipment that runs from a single cell

Lithium-Ion (Li+) battery. The converter can supply

1200mA of load current from a 2.5V to 5.5V input

voltage. The output voltage can be regulated as low as

0.6V. The LP6302 can also run at 100% duty cycle for

low dropout applications.

The LP6302 is available in a 16-lead 3mm*3mm TDFN

package and is rated over the -40°C to 85°C temperature

range.
