| DC-to-DC Converter Modules MES1206 JUN 2003 MES1206 DC/DC Converter General Description MES1206 is a DC/DC converter which can be used to supply DC output from a commercial power supply (85 to 265 VAC). of Using these module enable simple, easy drive LEDs, and other electronic microcomputers, components without using a transformer. It also allows set PCBs to be kept compact and lightweight, with extremely few attachments. as household power supplies. It can accommodate the 100VAC~200VAC power supplies used Application Small multi-purpose power supply Stand-by power supply aimed at low power consumption when loaded light Insulated-type DC-DC converted Features Wide Input Range : FREEVOLT (AC 85V ~ 265V) A switching power supply can be made easily by adding simply external circuit Permits reduction of power consumption at low loads(when in stand-by) Able to deal with inputs of worldwide areas Ultra-compact size attained by application of high-density mounting technique Application of the unique molding technique features Compliance with various safety regulations from the compact size Humming is prevented when intermittent oscillation Over Temperature Protection Output Short Circuit Protection Over Load Protection Absolute Maximum Ratings (Ta = 25C) Characteristics Input Voltage Output Voltage Maximum Output Current Peak Output Current ESD Endurance Maximum Surface Temperature Operating Temperature Range Storage Temperature Range (c) Copyright 2003 Mobilelectron Co., Ltd.

Capacitance : 0.1F~0.22F, Rated voltage : 400V or higher C2 For noise terminal voltage reduction Film capacitor or ceramic capacitor. Reduce the noise terminal voltage. The constant value should be evaluated in the set. C3 Capacitor for Safety Capacitance : 1nF~4.7nF, Rated voltage : 400V or higher Capacitance : 470F~1000F, Rated voltage : 25V or higher C4,C5 Capacitor for output voltage smoothing ESD is 0.4 max. Ripple current is 0.25Arms above. Output noise voltage is influenced. Please evaluate it in the actual set. C6 Bypass Capacitor for high frequency noise Capacitance : 10nF~100nF, Rated voltage : 50V or higher Film capacitor or ceramic capacitor. Reduce the high frequency noise terminal output. L : 4.7~10H, Allowable current : 2A or higher L1 Choke Coil Please use the one that is hard to be magnetic saturated even in the high temperature. In the absolute maximum ratings, the reverse peak voltage should be 500V or higher, the average rectifying current should D1 Rectifier Diode be 1A or higher, and the peak surge current should be 1 0A or higher. (Full-wave rectifier can be used in out part.)
