摘要
目前,电子产品工作离不开电源,因此介绍了一种基于PN8370的开关电源,主要用于微型断路器电动操作系统。当系统不工作处于待机状态时,要求电源处于稳压输出11.5V、10μA的低功耗状态;当出现线路故障系统开始工作,要求电源从11.5V、10μA平稳过渡到11.5V、1 A,从而驱动马达动作断开故障线路。
The switching power supply based on PN8370 introduced in this paper is mainly used in the electric operating system of miniature circuit breaker.When the system does not work and is in standby state,the power supply is required to be in the lowpower state of 11.5 V 10μA output voltage stabilization;when a line fault occurs,the system starts to work,and the power supply is required to smooth transition from 11.5 V 10μA to 11.5 V 1 A,thus driving the motor to disconnect the fault line.
