AS1310数据手册集成电路（IC）的DCDC开关稳压器规格书PDF

描述 Description

The AS1310 contains two independent 1.5MHz constant frequency current mode PWM step-down converter. Each converter 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. Each converter can supply 0.8A (max.) of load current from a 2.5V to 6.5V input voltage. The output voltage can be regulated as low as 0.6V, The AS1310 can also run at 100% duty cycle for low dropout applications.\r
\r
The AS1310 is available in a low profile (1mm) 10-pin, TDFN package.
