产品概述 返回TOP
CXAC8501 Series is a high performance green-energy offline power supply controller. It features a scalable driver for driving external NPN or MOSFET transistors for line voltage switching. This proprietary architecture enables many advanced features to be integrated into a small package (TO-92 ), resulting in lowest total cost solution. The CXAC8501 design has 6 internal terminals and is a pulse frequency and width modulation IC with many flexible packaging options. One combination of internal terminals is packaged in the space-saving TO-92 package (A/B versions) for 65kHz or 100kHz switching frequency and with 400mA or 800mA current limit. Consuming only 0.15W in standby, the IC features over-current, hiccup mode short circuit, and under-voltage protection mechanisms. The CXAC8501 is ideal for use in high performance universal adaptors and chargers.
