Product Descriptions
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 LithiumIon (Li+) Battery. Each channel of the MP2102 can supply 800mA of load current from a 2.5V to 6V input voltage. Both output voltages can be regulated as low as 0.6V.
The device features integrated high-side switches and synchronous rectifiers for high efficiency step-down conversion without the need for external Schottky diodes. With peak current mode control and internal compensation, the MP2102 can be stabilized with ceramic capacitors and small inductors. Fault condition protection includes cycle-bycycle current limiting and thermal shutdown.
The MP2102 is available in small 10-pin QFN with exposed pad and 10-pin MSOP packages.
