In order to improve the power supply stability,low breakdown,simultaneously could simplify the circuit,saving cost,Introduced a new power integrated blocks ICE2A165,Using ICE2A165 designed a switching power supply.ICE2A165 contains switch Field Effect Transistor,can directly incentive switch transformer work,again complementary with precision three end comparator and photoelectric coupler is constructed high-performance switching power supply.Through the reasonable choice parameters of external components,can make the switching power supply with wide voltage range,and comparison sensitive protective properties.This broadened application ability of power supply to power grid,and reduces the chance to malfunction.This broadens the applicability of the circuit to power grid,and reduces the probability of failure.Practice shows that the switch power based on ICE2A165 in 110 ~ 240V alternating current stable output + 5V and + 12V,Working for a long time,the circuit is very stable and reliable.
