TPS542A50 - Texas Instruments

TPS542A50 Synchronous Buck Converter

The TPS542A50 is a high-efficiency synchronous buck converter with differential remote sense and I2C. This device features fixed-frequency, voltage-control mode with pinstrap selectable internal compensation for reduced system cost and complexity. The PWM can be synchronized to an external clock through the SYNC pin. Other key features include PFM for high .
