TPS55010EVM-009 DC/DC Converter Evaluation Module

Texas Instruments' introduces isolated DC/DC converter for low-noise 2 W power supplies

Texas Instruments' TPS55010 is a transformer driver designed to provide isolated power for isolated interfaces, such as RS-485 and RS-232, from 3.3 V or 5 V input supply. The device uses fixed frequency current mode control and half bridge power stage with primary side feedback to regulate the output voltage for power levels up to 2 W. The switching frequency is adjustable from 100 kHz to 2000 kHz so solution size, efficiency and noise can be traded off. The switching frequency is set with a resistor or is synchronized to an external clock using the RT/CLK pin. To minimize inrush currents, a small capacitor is connected to the SS pin. The EN pin is used as an enable pin or to increase the default input UVLO voltage from 2.6 V. The TPS55010EVM-009 is a fully assembled and tested circuit for evaluating the TPS55010 Isolated DC/DC converter with integrated FETs. The TPS55010EVM-009 uses fixed frequency current mode control and a half bridge power stage with primary side feedback to regulate the output voltage for power levels up to 2 W.
