ADI is the world‘s leading supplier of high-performance signal processing solutions, including another advanced digital power controller ADP1051 with integrated PMBus interface, which is aimed at ultra-compact, high-density isolated DC-DC power systems with parallel/redundant ability.
The ADP1051 is an extremely versatile digital controller with 6 PWM (pulse width modulation) logic outputs that can be programmed through the PMBus interface using an easy-to-use graphical user interface (GUI). The device supports energy-efficient topologies with built-in full-bridge and active-clamp forward-variable functions, precise drive timing and secondary-side synchronous rectifier control. Energy efficiency can be further optimized with adaptive dead-time compensation, improving efficiency over the load range and in programmable light-load modes, while the device‘s low power consumption (<100mW) further reduces system standby power losses. The ADP1051 integrates a feature-rich PMBus command set, including the ability to accurately read input and output power consumption measurements, enabling the end user to implement intelligent system management to optimize energy efficiency. The small 4 x 4 mm LFCSP package makes the ADP1051 ideal for high-density, ultra-compact isolated DC-DC power modules or embedded designs such as networking, communications, and industrial applications (typically over 100 W).
The ADP1051 power controller is easily programmable through an intuitive graphical user interface, allowing customers to design and save settings in highly reliable internal EEPROM memory. The ADP1051 integrates features that enable robust parallel and redundant operating systems to meet customer requirements for high availability and wider current regulation range. The device provides master/slave synchronization, reverse current protection, and pre-bias start-up for accurate passive or falling current sharing between supplies, and features a patented technology that recognizes and safely shuts down in parallel operation mode Disconnect the faulty power supply.
Key features and benefits of the ADP1051:
1. Small 4 x 4mm package supports ultra-compact isolated DC-DC design;
2. Feature-rich programming and telemetry PMBus command set to support intelligent power management and efficiency optimization;
3. A digital control loop integrating 6 PWM logic signals can drive a high-efficiency power supply topology with controlled synchronous rectification;
4. Adaptive dead time compensation and light load mode;
5. Stable parallel working scheme for high availability applications requiring redundancy, including precise drop current sharing, pre-bias start-up, reverse current protection and overvoltage protection under certain conditions;
6. GUI programming capabilities help simplify usage and shorten time to market.
Complementing the ADP1051 digital controller are ADI‘s MOSFET drivers, iCoupler® digital isolators (for isolated power systems), and the ADP1047 and ADP1048 power factor correction digital controllers (for AC-DC systems). These devices facilitate easy implementation of intelligent power management to improve energy efficiency.
