ADP1051 Product details

GENERAL DESCRIPTION
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). The device includes adaptive dead time compensation to improve efficiency over the load range, and programmable light load mode operation, combined with low power consumption, to reduce system standby power losses.

    6 pulse-width modulation (PWM) logic outputs with 625 ps resolution
    Switching frequency: 49 kHz to 625 kHz
    Frequency synchronization as master and slave device
    Multiple energy saving modes
    Adaptive dead time compensation for efficiency optimization
    Low device power consumption: 100 mW typical
    Direct parallel control for power supplies without OR’ing devices Accurate droop current share Pre-bias startup Reverse current protection Conditional overvoltage protection
    Extensive fault detection and protection
    PMBus compliant
