Description
General part information
TPS542A50 Series
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 light load efficiency, low shutdown quiescent current draw, adjustable UVLO through the EN pin and monotonic start up into pre-biased conditions. This device also features an I2C interface for device configuration and output voltage adjustment. The TPS542A50 is a lead-free device. It is fully RoHS compliant without exemption.
