MP2117 1.25MHz, 2.2A Synchronous Step-Down Switcher

Product Detail

The MP2117 is an internally compensated 2.2A synchronous step-down switcher. The operating frequency is internally set at 1.25MHz. MP2117 is ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) Battery. The MP2117 can provide up to 2.2A continuous load current from a 2.5V to 6V input voltage. The output voltage can be regulated as low as 0.6V. 100% duty cycle provides low dropout operation that extends operating time in battery-operated systems. The MP2117 features an integrated high side switch and synchronous rectifier for high efficiency. With peak current mode control and internal compensation, the MP2117 can be stabilized with ceramic capacitors and small inductors. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown. MP2117 is available in the small 10-pin 3mmx3mm QFN and SOIC-8 packages.
