LED driver with adjustable light output now features additional protection functions, including open and short circuit detection!
This product enables dimming by adjusting the duty cycle of the rectangular wave input to the dimming terminal (DIM) and allows for free setting of the LED current through an external electrical setting resistor. By adjusting the off time with an external resistor and capacitor connected to the CT terminal, energy can be recovered through an externally connected inductor, thereby saving power consumption. As a safety feature, it is equipped with a function that detects when the LED connection is open or shorted to the power supply and outputs an abnormal signal. Additionally, it has a UVLO function to prevent malfunction below 4V and also includes an overheating protection circuit.

Company information
Isahaya Electronics began production of small signal transistors in 1973 and has evolved its semiconductor technology into design technologies for gate drivers and DC/DC converters. In recent years, the company has also focused on developing high-efficiency, high-power-factor power supply technologies to contribute to carbon neutrality. (Three-phase PFC, 1500V input compatible DC/DC converters, bidirectional converters, etc.) Meanwhile, to meet diverse needs, small signal transistors have also evolved with enhanced functionality and integration, expanding the lineup of high-voltage, high-current transistors, MOSFETs, and analog ICs.
