AS1301
1.5MHz, 800mA Synchronous Step-Down Converter
DESCRIPTION
The AS1301 is a 1.5MHz constant frequency current
mode PWM step-down converter. The device integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. It is ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) battery. The AS1301 can supply 800mA of load current from a 2.5V to 6.5V input
voltage. The output
voltage for the AS1301-adj can be regulated as low as 0.6V, while the output
voltage of the AS1301-1.8 is fixed at 1.8V. The AS1301 can also run at 100% duty cycle for low dropout applications. The AS1301 is available in a low profile (1mm) 5-pin, TSOT23 package.
