Diodes Incorporated AP3917x Step Down Power Switchers
Diodes Incorporated AP3917x Step-Down Power Switchers are universal AC voltage switchers with a non-isolated buck or offline flyback solution. These Diodes Incorporated power switchers coordinate with a single-winding inductor and provide a low Bill Of Material (BOM) cost solution. The AP3917x switchers feature over-temperature protection, under-voltage lock function, output short protection, overload protection, and open-loop protection. These power switchers include an 8.2V to 8.8V supply voltage range and a -40°C to 125°C ambient temperature range. The AP3917x switchers provide a low audible noise solution with a universal 85VAC to 264VAC input range. These power switchers are ideal for IoT, industrial controls, non-isolated home appliances, standby, and auxiliary.
