PWM controller IC for generating dimming signals with adjustable duty ratio and frequency!
The "RT8H114C" generates pulse signals with adjustable duty ratio and frequency. Therefore, it is an ideal product for dimming LEDs based on the duty ratio of the on-time or for use with ICs that require pulse signal input. The duty ratio of the output signal can be set by adjusting the voltage at the DUTY terminal, and the frequency can be set by adjusting the values of the resistor and capacitor connected to the CT terminal. Additionally, by applying input voltage to the ON/OFF terminal, it is possible to forcibly drop the output to 0V. We also offer a free evaluation demo board that can be combined with the current driver IC (RT8H144C). Please feel free to contact our sales team when you need it!

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.
