Product Summary

The MP2105DJ evaluation board is designed for low dropout step down converter applications. The MP2105DJ implements the MP2105 1MHz Fixed Frequency, Current Mode, PWM step-down converter. The MP2105DJ 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. Applications are (1)Cellular and Smart Phones; (2)Microprocessors/DSP Core Supplies; (3)PDAs; (4)MP3 Players; (5)Digital Still and Video Cameras; (6)Portable Instruments.

Parametrics

MP2105DJ absolute maximum ratings: (1)Input Voltage Range VIN: 2.5 to 6.0 V; (2)Output Voltage VOUT: 1.8 V; (3)Load Max IOUT: 800 mA.

Features

MP2105DJ features: (1)High Efficiency: Up to 95%; (2)800mA Available Load Current; (3)2.5V to 6V Input Voltage Range; (4)Output Voltage as Low as 0.6V; (5)100% Duty Cycle in Dropout; (6)Short Circuit Protection; (7)Thermal Fault Protection; (8)<0.1μA Shutdown Current; (9)Programmable Enable Control.
