The CAT3647HV3-GT2 is a CAT3647HV LED driver, a type of pulse width modulation (PWM) integrated circuit (IC) used to provide power to Light Emitting Diodes (LEDs). This IC is designed to provide improved internal power supply efficiency while driving multiple high brightness white LEDs in series. It has a wide operating temperature range and can withstand power spikes up to 25V. It is suitable for use in a variety of applications, including automotive lighting, consumer electronics, tablet PCs, and industrial lighting.

The CAT3647HV3-GT2 uses an on/off switch control input frequency of 300KHz or less, with a two-channel 4-way phase-shift PWM dimming control system. It is capable of supplying up to 1.4A per channel at 25V, and supports PWM dimming from 0%–100%. The IC is designed for use in systems with a wide input voltage range from 3V–25V, and offers a wide operating temperature range of -40°C to 150°C.

The working principle of the CAT3647HV3-GT2 LED driver is to use pulse width modulation (PWM) to regulate the amount of current provided to the LED. It does this by using a switching transistor that is turned on and off based on the PWM input. The width of the pulses determines the amount of current supplied to the LED and is regulated based on the peak current value that is set externally. This IC is designed to provide efficient, smooth control of the LED brightness without sacrificing power supply efficiency.
