Compared to the INV3121, which requires multiple ICs to be used in parallel for high current applications, the INV3123 provides a simpler circuit design and lower implementation cost. In addition, the INV3123 is packaged in a TO252-5L package with better heat dissipation (with heatsink on the bottom). This series of ICs is the world's first dedicated ripple suppression chip for LED lighting with low power consumption and multiple protection functions.
In addition to inheriting the original LED pin voltage limit function, LED peak current limit function and over temperature protection function of INV3121, the INV3123 series chip further enhances the functions of LED short circuit protection, LED hot swap protection, etc. Reliability and stability. At the same time, INV3123 greatly reduces the normal operating current of the control chip and the on-resistance of the built-in MOSFET, which effectively reduces the power consumption of the IC itself.
The INV3123 is especially suitable for wide input range, LED lighting driver back-ends with single-stage PFC functionality. Such drivers often have the drawback of excessive output current ripple, and excessive current ripple can cause significant LED power frequency strobe problems. INV3123 effectively suppresses this ripple current and thus compensates for the defects of power frequency strobe. Compared with the traditional two-stage driving scheme to suppress ripple current, INV3123 adopts a simpler design, lower cost and higher cost performance. It can be widely used in small and medium power LED indoor lighting places (such as downlights, panel lights, fluorescent lamps, Ceiling lights, etc.), especially in environments where the stability of the light source is high.
