DK8712AD Datasheet | Dongke Semiconductor

Description The DK87xx AD is an AC-DC power converter based on asymmetric half-bridge topology, which integrates half bridge Ga N devices. The DK87xx AD recycles leakage inductance energy to enable primary side ZVS and secondary side ZCS. Therefore, system overall efficiency is improved. Soft switches also can reduce power FET stress, reduce switching losses and reduced EMI interference (EMI). The DK87xx AD greatly simplifies system design and manufacture of AC-DC converters, especially those requiring high efficiency and high power density. The DK87xx AD has prehensive protection functions such as: overload protection(OCP), output over voltage protection(output OVP), output short circuit protection(output SCP), VCC over and under voltage protection(VCC UVLO and VCC OVP), VS abnormal protection, cycle-by-cycle current limit protection, over temperature protection(OTP), etc. The DK87xx AD adopts DFN8- 8 packaging. - Features - HB Ga N FETs integrated - AHB control circuit and half-bridge driver integrated - Up to 800KHz switching frequency - Standby power consumption less than 50m W - Self adaptive dead time - Very few peripheral ponents - Less voltage stress over secondary side - Built-in frequency jittering - Built-in HV start-up and X-capacitor discharge - Halogen-free and ROHs-pliant - DFN8- 8 packaging - Applications - High power density SMPS power adapter/charger - Laptop adapter, tablet adapters, TV power supply, electrical cycle charger - munication power supply - LED power supply .dkpower.cn - Order Information DK87xx AD series Marking DK 2301 A B C 8710 A D T 01 Note DK Semiconductor 2023 1th Batch of Production Internal Code Internal Code Internal Code Product No. Internal Code Encapsulated Code Testing Code - Product Information Order Codes DK8710AD DK8712AD DK8715AD DK8718AD Package DFN8- 8 DFN8- 8 DFN8- 8 DFN8- 8 Typical Power With PFC-DC380V 100W 120W 150W 180W .dkpower.cn - Typical...
