The TPS542A52 is a high-efficiency synchronous buck converter with differential remote sense. 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. The TPS542A52 is a lead-free device. It is fully RoHS compliant without exemption.
