LP6302
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.
