KP1402ASSGA

0-10v Linear Dimming Isolated PWM Dimming Chip

The KP1402ASSGA is a highly accurate and fully configured dimmer signal converter. The chip can detect different dimming input signals (including 0/1-10V, 10-0/1V, 0/1-5V, 5-0/1V voltage dimming signals, 0-100% duty cycle PWM signals, and simple resistance dimming signals), and convert the input signal to the corresponding duty cycle PWM signal. Used to adjust the output current of the LED driver.

KP1402ASSGA has a variety of flexible configuration functions through the external resistor, including the output frequency can be set, different input signal detection current can be set, the corresponding input dimming signal voltage or duty cycle can be set when DIM OFF, the minimum output duty cycle can be set, and the dimming clamp site can be set. Reversible logic dimming can be set at 0-5/10V and PWM dimming.

The KP1402ASSGA provides a very wide operating voltage of 12V to 100V, making the chip power supply circuit much simpler. The KP1402A also incorporates overheat protection, which stops output dimming signals when the temperature is too high to improve system reliability.
