EMH7601 Datasheet | Elite Semiconductor Microelectronics Technology

ESMT/EMP DC/DC Boost Converter General Description EMH7601 designed with high efficiency step up DC/DC converter for portable devices applications. It Features with extreme low 26μA quiescent current with no load which is the best fit for extending battery life during the standby mode. Battery Powered, High Efficiency Synchronous Features - - - - - - Single or dual battery operation Achieve 93% efficiency Output Current up to 500m A Reference voltage 1.195V Typical Iq 26μA with no load No Schottky diode needed Shutdown current < 1μA Excellent Line and Load Transient Response The start-up voltage is 0.93V typically with operating voltage down to 0.7V. With Synchronous structure, it does not need any external Schottky diode. The peak current is limited to 1A for quick turn on. - - Applications - - - - Blue-Tooth devices Cellular and Smart Phones Personal multi-media Player (PMP) Wireless networking Hand-Held Devices with 1 to 3-Cell of Ni MH/Ni Cd Batteries - - Digital Still Cameras Portable applications This product can provide 500m A load current and still maintained at least 70% efficiency and above 90% efficiency when at 100m A load current. The EMH7601 is available in SOT-23-5 & TDFN-6 package, With Ro HS pliance. - Typical Application Efficiency vs. Load Current 100.0% 90.0% 80.0% Efficiency (%) 70.0% 60.0% 50.0% 40.0% 30.0% 20.0% 10.0% 0.0% 0.01 0.1 1 10 100 1000 Output Current (m A) Fig. 1 Fig. 2 Elite Semiconductor Memory Technology Inc./Elite Micro Power Inc.
