The DK5030 with SOP-8 AC-DC Controllers & Regulators ROHS is a family of offline switcher ICs designed to control high-efficiency AC-DC switch mode power supplies (SMPS). The DK5030 family is suitable for use in low, mid and high-power applications that require low BOM cost, power optimization, and accurate current sense control. This IC is manufactured by DongKe, a Chinese electronics company that specializes in the development and production of analog integrated circuits. The DK5030 has a wide input voltage range, making it ideal for designs where input voltage variations are expected over a wide range. The wide power on/off time selection of 400ms/850ms/1.4s/2.8s helps to balance performance and system protection. These adjustable protection features guard against overload, over temperature, UVLO and SCP. For output voltage accuracy, this part offers up to ±1% line regulation and ±1% load regulation. The SOP-8 package and 0.5A OCP makes this part suitable for a wide variety of applications. The ROHS marking indicates that the product meets the requirements of the Restriction of Hazardous Substances Directive.
