[原创] ADI ADP1051高效低成本400W电源参考设计

ADI公司的ADP1051是用于隔离式电源的带有PMBus接口的数字控制器,具有6个PWM逻辑输出,分辨率625ps,开关频率49kHz到625kHz,具有高可靠性,高效率,高集成度的特点,主要用在高密度隔离式DC/DC电源,中间总线转换器,并行电源系统和服务器,存储,工业,网络和通信基础设备.本文介绍了ADP1051主要特性,功能框图和几种典型应用电路,以及采用ADP1051的高效低成本400W电源设计主要特性,框图和主要指标,电路图,材料清单和PCB设计图.

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.
