4-V to 18-V input, voltage mode, 15-A synchronous SWIFT™ step-down converter with I2C interface

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.
