MP2109 General Description

The MP2109 contains two independent 1.2MHz constant frequency, current mode, PWM step down converters. Each converter integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. The MP2109 is ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) battery. Each converter can supply 800mA of load current from a 2.5V to 6V input voltage. The output voltage can be regulated as low as 0.6V. The MP2109 can also run at 100% duty cycle for low dropout applications.

MP2109 Maximum Ratings

V_IN1/IN2 to GND ........................ 0.3V to +6.5V
V_SW1/SW2 to GND............... 0.3V to V_IN + 0.3V
V_FB1/FB2, V_EN1/EN2 to GND ........ 0.3V to +6.5V
Junction Temperature............................+150
Lead Temperature ............................... +260
Storage Temperature .............65 to +150
