TD1410C

T  echcode® DATASHEET       1.8A 380KHz 20V PWM Buck DC/DC Converter TD1410C General Description  Features    The TD1410C is a 380 KHz fixed frequency monolithic step down switch mode regulator with a built in internal Power MOSFET. It achieves 1.8A 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 circuit protection function are built inside. An internal compensation block is built in to minimize external component count. z 1.8A Constant Output Current z 140mΩ RDSON Internal Power PMOSFET Switch z Up to 95% Efficiency z Fixed 380KHz Frequency z Wide 3.6V to 20V Input Voltage Range z Output Adjustable from 1.222V to 18V 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 TD1410C serves as ideal power supply units for Applications  portable devices.   z Portable DVD z LCD Monitor / TV z Battery Charger z ADSL Modem z Telecom / Networking Equipment  Package Types                   Figure 1. Package Types of TD1410C  T  echcode®       1.8A 380KHz 20V PWM Buck DC/DC Converter Pin Configurations  DATASHEET TD1410C Pin Description      Figure 2 Pin Con...
