China KP1191SPA Manufacturer, Supplier, Factory

​For high power density, high power output fast charge needs, Sillij launched a high-performance PFC+LLC combination controller SY5055, which sealed the front BOOST PFC and the rear LLC controller, making the peripheral circuit more concise, saving costs and also conducive to improving the power density of the entire power solution.

This DEMO board is a high performance nonisolated 600W constant current LED driver which is controlled by KP1469.Besides the multi-protection function (OVP, SCP, OTP), this demo also has very good efficiency, load regulation, low standby power loss and wide dimming range.

The demo board is designed to demonstrate a highperformance 50WLED filament lamp solution with a full input voltage range. The demonstration board is realized through a highly integrated high-frequency direct drive gallium nitride boost boost PFC constant current controller KP1352, with 650V power GaN FET.

KP201 is a high performance current mode PWM controller for offline flyback converter applications. The IC supports DCM and CCM operation mode.

We provide diversified integrated chip solutions such as AC-DC, DC-DC, LDO and current limiting switch for smart meter applications to meet the high reliability and high performance requirements of meter applications.

In the modern era of electronics, ACDC Constant Current Chips have become indispensable in powering devices that demand stable and efficient energy conversion. These chips act as the essential link between alternating current (AC) input and direct current (DC) output, ensuring that electronic devices receive a constant, regulated current supply regardless of voltage fluctuations. This feature is crucial for maintaining performance stability and extending the lifespan of devices such as LED lighting, power adapters, battery chargers, industrial control systems, and communication equipment.
