Dcription
The MP2102 is a dual-output, internally compensated, 1.5MHz fixed frequency PWM step-down converter. It is ideal for powering portable equipment from a single cell Lithium-Ion (Li+) Battery. Each channel of the MP2102 can supply 800mA of load current from a 2.5V to 6V input voltage. Both output voltag can be regulated as low as 0.6V. The device featur integrated high-side switch and synchronous rectifiers for high efficiency step-down conversion without the need for external Schottky diod. With peak current mode control and internal compensation, the MP2102 can be stabilized with ceramic capacitors and all inductors. Fault condition protection includ cycle-by-cycle current limiting and thermal shutdown. The MP2102 is available in all 10-pin QFN with exposed pad and 10-pin MSOP packag.
