ADI ADP5053 Altera FPGA电源解决方案
ADI公司的ADP5053是四路高性能DC/DC降压转换器,并集成了监测电路,看门狗定时器和手动重置,输入电压4.5V-15.0V,全温度范围内的输出精度±1.5%,可调开关频率250kHz-1.4MHz,固定/可调输出,主要用在小型基站,FPGA和处理器电源,安全和监视,医疗电子.本文介绍了ADP5053主要特性,框图, 典型应用电路图以及多种Altera FPGA电源解决方案详细电路图和材料清单.
The ADP5053 combines four high performance buck regulators, a supervisory circuit, a watchdog timer, and a manual reset in a 48-lead LFCSP package that meets demanding performance and board space requirements. The device enables direct connection to high input voltages up to 15.0 V with no preregulators.
Channel 1 and Channel 2 integrate high-side power MOSFET and low-side MOSFET drivers. External NFETs can be used in low-side power devices to achieve an efficiency optimized solution and deliver a programmable output current of 1.2 A, 2.5 A, or 4 A. Combining Channel 1 and Channel 2 in a parallel configuration can provide a single output with up to 8 A of current.
Channel 3 and Channel 4 integrate both high-side and low-side MOSFETs to deliver an output current of 1.2 A.
