The 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 at approximately 65kHz. In middle load conditions, the IC enters green mode to improve system efficiency through frequency foldback. A minimum switching frequency of about 20kHz is set to avoid audible noise. In no-load or light-load conditions, the IC enters burst mode to minimize standby power.
This controller features internal slope compensation for stable Peak-Current Mode control and internal line compensation for constant output power limit over a universal line voltage range. Comprehensive protection features are included, such as cycle-by-cycle current limit (OCP), VCC Overvoltage Protection (VOVP), internal OTP, and Overload Protection (OLP).
The AP3125AKTR-G1 is supplied in a mini-size SOT26 package, suitable for surface mounting. It is pin-to-pin compatible with AP3105NA/NV/NL/NR series. The device is totally lead-free and fully RoHS compliant, as well as halogen and antimony free.
Applications include switching AC-DC adaptors/chargers, ATX/BTX auxiliary power, set-top box power supplies, and open-frame switching power supplies.
