It achieves 2A continuous output current over a wide input supply range with excellent load and line regulation. The device includes a voltage reference, oscillation circuit, error amplifier, internal PMOS and etc. The PWM control circuit is able to adjust the duty ratio linearly from 0 to 100%. An enable function, an over current protection function and a short c ircu i t protection function are built inside. An internal compensation block is built in to minimize external component count. The EC9410 serves as ideal power supply units for portable devices. 2A Constant Output Current 140mΩ RDSON Internal Power PMOSFET Switch Up to 95% Efficiency Fixed 380KHz Frequency Wide 3.6V to 20V Input Voltage Range Output Adjustable from 1.222V to 18V Built in Frequency Compensation Built in Thermal Shutdown Function Built in Current Limit Function SOP8 Package is Available The minimum dropout up to 0.3V Applications z z z z z Portable DVD LCD Monitor / TV Battery Charger ADSL Modem Telecom / Networking Equipment Function Block E-CMOS Corp.
