DiodesZetex AP3108LSS9-13, PWM Controller, 65 kHz 9-Pin, SSOP-9

The DiodesZetex makes a current mode PWM controller specially designed for offline power supply that requires ultra-low standby power, high-power density and comprehensive protection. The AP3108LS coordinating with Diodes Incorporated’s secondary side controller, such as the AP4320, can be applied in the situation that requires for constant CC and constant CV. The AP3108LS integrates a VCC LDO circuitry, allowing the LDO to regulate the wide range VCC_IN, which is rectified from auxiliary winding to an acceptable value. This makes the AP3108LS a good choice in wide range output voltage application. There are also versatile system protections provided by AP3108LS, such as secondary side OVP, secondary side UVP, constant output current limit, cycle-by-cycle current limit, brown-out protection, programmable external OTP, etc.

Current mode control, high-voltage start-up Embedded VCC LDO to guarantee wide range output voltage Constant, low output current in output short situation Low VCC charge current reduces standby power in output short situation Internal Slope Compensation and soft start during start-up process
