Product Description

The EV28114 evaluation board is designed for low dropout step down converter applications. It implements the MP28114 1.7MHz Fixed Frequency, Current Mode, PWM step-down converter. The device integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. It is ideal for powering portable equipments that runs from a single cell Lithium-Ion (Li+) Battery. It can supply 600mA of load current from a 2.5V to 6V input voltage. The output voltage can be regulated as low as 0.6V. In 100% Duty Cycle Dropout operation, it works with minimum input voltage as low as output voltage.

IC Details

The MP28114 is a 1.7MHz constant frequency, current mode, ultra-small PWM step-down converter. The device integrates a main switch and a synchronous rectifier for high efficiency and eliminates the needs for an external schottky diode. It is ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) battery. The MP28114 can supply 600mA of load current from a 2.5V to 6V input voltage. The output voltage for the MP28114DG can be regulated as low as 0.6V, while the output voltages of the MP28114DG 1.5, MP28114G 1.8, and MP28114DG 3.3 are fixed at 1.5V, 1.8V, and 3.3V, respectively. The MP28114 can also run at 100% duty cycle for low dropout applications. The MP28114 is available in an ultra-small 2x2mm QFN package.
