Linear LTC3216 42V 2．5A无损耗输入PowerPath电源解决方案
Linear公司的LTC3216是高效无损耗输入PowerPath降压电源稳压器,输入电压2.4V-42V,输出电压0.818V 到VIN输出电流2.5A,突发模式静态电流2uA,主要用在手持工业/通信测试设备,电池和超级电容备份电源,带电池备份的汽车电源以及不间断电源(UPS).本文介绍了LTC3216主要特性,框图,多种应用电路,以及演示板DC2215A测试图,电路图和材料清单.
The LTCR3126 is a high efficiency synchronous buckconverter with an internal no-loss PowerPath™ supportingseamless operation from two separate input power sources.
Pin-selectable ideal diode-OR and priority input modeswith user programmable undervoltage lockout thresholdsprovide full control over the transition between the inputpower sources. The fast, automatic switchover providedby the internal PowerPath eliminates the need for hold-upcapacitors and minimizes disturbances on the output rail.An active input channel indicator and independent inputand output power good signals provide complete feedbackof the power system status.
