Non-Isolated Buck Switchers from Diodes Incorporated Provide High-Voltage AC-DC Conversion with Low Standby Current for Alway...

Business Wire
Diodes Incorporated (Nasdaq: DIOD) today announced the AP3917
family of universal AC-DC, non-isolated buck (step-down) power
switchers for low-power applications, such as small appliances and
IoT endpoints powered by an offline supply. Family members include
the AP3917B (170mA nominal load), AP3917C (270mA), and AP3917D
(370mA).
The need for direct, non-isolated AC-DC conversion in a small
form factor, with high levels of efficiency and low standby
current, is increasing due to the proliferation of small household,
office, and industrial appliances that operate as standalone
devices or as part of the IoT.
The AP3917 family of buck switchers is designed to provide
highly efficient, offline power conversion for light-load
applications. Discontinuous and continuous conduction modes are
both supported.
The AP3917 buck switcher can convert a full-wave rectified, AC
input voltage between 85VAC and 265VAC to a nominal 8.0V DC output.
Its non-isolated design requires no external transformer and very
few external components, saving space and BoM cost.
With a no-load power consumption of less than 30mW, the AP3917
buck switchers are particularly suitable for small appliances that
operate in standby mode for prolonged periods when connected to an
AC outlet. Its low-power credentials and small solution size also
make the AP3917 appropriate for IoT devices that are always
connected but not always active.
