GENERAL DESCRIPTION

FEATURES

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 circuit protection function are built inside. An internal compensation block is built in to minimize external component count. The TD7580 serves as ideal power supply units for portable devices. 4A Constant Output Current 80mΩ RDSON Internal Power PMOSFET Switch Up to 95% Efficiency Fixed 240KHz Frequency Wide 3.6V to 23V Input Voltage Range Output Adjustable from 1.222V to 21V Built in Frequency Compensation Built in Thermal Shutdown Function Built in Current Limit Function SOP-8 Package is Available The minimum dropout up to 0.3V
