The Future of Analog IC Technology MP2125 Dual 1.5A, 1.2MHz Synchronous Step-Down Converter DESCRIPTION The MP2125 is a fully integrated dual PWM step-down converter with built-in internal power MOSFETs. It is ideal for powering portable equipment that runs from a single cell LithiumIon (Li+) Battery, with an input range from 2.7V to 6V. The MP2125 can provide up to 1.5A of load current with output voltage as low as 0.8V for each output. It can also operate at 100% duty cycle for low dropout applications. With peak current mode control and internal compensation, the MP2125 is stable with ceramic capacitors and small inductors. Fault condition protection includes cycle-bycycle current limiting and thermal shutdown. MP2125 is available in the small 14-pin 3mmx4mm QFN package.
