Analog Devices ADP1051

The ADP1051 is an advanced digital controller with a PMBusTM interface targeting high density, high efficiency dc-to-dc power conversion. This controller implements voltage mode control with high speed, input line feedforward for enhanced transient and improved noise performance. The ADP1051 has six programmable pulse-width modulation (PWM) outputs capable of controlling most high efficiency power supply topologies, with added control of synchronous rectification (SR).
