This controller implements voltage mode control with high speed, input line feed-forward for enhanced transient and improved noise performance. The ADP1051 has 6 programmable PWM outputs capable of controlling most high efficiency power supply topologies with added control of synchronous rectification. The device includes adaptive dead-time compensation to improve the efficiency over the load range and programmable light load mode operation combined with low device power consumption to reduce system standby power losses. The ADP1051 implements several features to enable a robust system of parallel and redundant operation for customers that require high availability or parallel connection. The device includes master/slave synchronization, reverse current protection and pre- bias start-up, accurate current sharing between power supplies and conditional overvoltage techniques to identify and safely shutdown an erroneous power supply in parallel operation mode. The ADP1051 is based on flexible state machine architecture and is register programmed using an intuitive, graphical-user interface. The easy–to-use interface reduces design cycle time and results in a robust, hardware coded system loaded into the built-in EEPROM. The small size 4*4 mm LFCSP package makes the ADP1051 ideal for ultra-compact, isolated DCDC power module or embedded designs. Figure 1.
