The ADP1051 power controller is easily programmed using an intuitive graphical-user interface which enables customers to design and store settings in the high reliability, internal EEPROM memory. The ADP1051 implements several features to enable a robust system of parallel and redundant operation for customers that require high availability for increased current scaling. The device includes master/slave synchronization, reverse current protection and pre-bias start-up, accurate passive or droop current sharing between power supplies and a patented technique to identify and safely shutdown an erroneous power supply in parallel operation mode.
Key ADP1051 Features and Benefits:
• Small 4 x 4mm package enables ultra-compact isolated DC-to-DC design
• Extensive PMBus command set for programming and telemetry enabling intelligent power management and efficiency optimization
• Digital control loop with six logic PWM logic signals to drive high efficiency power supply topologies with controlled synchronous rectification
• Adaptive dead-time compensation and light load modes
• Robust parallel operating scheme for high availability applications requiring redundancy including accurate droop current share, pre-bias start-up, reverse current protection and conditional overvoltage protection
• GUI programmability promotes ease of use and reduces time to market
