The TPS563210ADDFR is a Switching Voltage Regulators, 17V Input, 3A Synchronous Step-Down Regulator in an 8-SOT-23-THIN package, manufactured by Texas Instruments. This device uses advanced Eco-mode to reduce external components in boost applications, programmable soft start functionality, and pulse-frequency modulation (PFM) and pulse-width modulation (PWM) to regulate output voltage. It also features integrated protection against over-current, over-voltage, and short-circuit conditions, as well as thermal shutdown. It operates over a temperature range of -40 to 85 °C.
