Beschreibung

The TPS55010 is a transformer driver designed to provide isolated power (see Table 2). The deviceoperates from 6 V down to 2.95 V. The device uses fixed-frequency current mode control and a halfbridgepower 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 to allow optimization of solution size,efficiency, and noise. The switching frequency is set with a resistor or is synchronized to an external clockusing the RT/CLK pin. To minimize inrush currents, a small capacitor can be connected to the soft-startpin. The EN pin can be used as an enable pin or to increase the undervoltage lockout (UVLO) of thedefault input from 2.6 V.
