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. z 2.2A Constant Output Current z 80mΩ RDSON Internal Power PMOSFET Switch z Up to 95% Efficiency z Fixed 380KHz Frequency z Wide 3.6V to32V Input Voltage Range z Output Adjustable from 1.222V to 30V z Built in Frequency Compensation z Built in Thermal Shutdown Function z Built in Current Limit Function z SOP-8 Package is Available z The minimum dropout up to 0.3V The TD3112 serves as ideal power supply units for APPLICATIONS
