AP3125AKTR-G1,Converter Offline Flyback Topology 65kHz SOT-26DescriptionThe DIODES™ AP3125A is a current mode PWM controller optimized for
high performance, low standby power, and cost-effective offline
flyback converters. The PWM switching frequency at normal operation
is internally fixed (about 65kHz). In middle load, the IC will
enter green mode to improve system efficiency with the help of
frequency foldback. A minimum switching frequency (about 20kHz) is
set to avoid the audible noise. In no load or light load, the IC
will enter the burst mode to minimize standby power. Furthermore,
the frequency dithering function is built-in to reduce EMI
emission. Internal slope compensation allows more stable
Peak-Current Mode control over wide range of input voltage and load
conditions. Internal line compensation ensures constant output
power limit over entire universal line voltage range. Comprehensive
protection features are included, such as cycle-bycycle current
limit (OCP), VCC Overvoltage Protection (VOVP), internal OTP,
Overload Protection (OLP), and pins’ fault protection. The
versatile latch functions can be implemented using a minimal number
of external components.
