The XRCWHT-L1-0000-00905 from ON Semiconductor is a highly efficient, controller-less, cost-effective LED driver optimized for non-dimmable white lighting applications. Powered by the latest topology and adaptive circuitry, the XRCWHT-L1-0000-00905 is the perfect choice for applications requiring dim-to-warm functionality. In this article, we’ll discuss the application field and working principle of the XRCWHT-L1-0000-00905.

The XRCWHT-L1-0000-00905 is optimized for use in a wide range of dim-to-warm and non-dimmable white lighting applications. It can be used for linear, track, and recessed lights, as well as in lamps, back-lighting systems, and down lights. The XRCWHT driver offers excellent power factor, high efficiency up to 90%, and over-temperature protection for safety and performance. The driver supports 0-10V dimming, and is available in a range of output current options from 25mA to 100mA.

The XRCWHT-L1-0000-00905 is based on a controller-less topology that eliminates the need for an external micro-controller. It features an adaptive circuitry, which makes it easy to adjust to changing output conditions. This adaptive circuitry enables the driver to adapt to different input voltages and automatically adjust the output current to match the LED loads. The adaptive circuitry also ensures that the driver maintains its high efficiency under varying conditions.

The XRCWHT-L1-0000-00905 utilizes pulse-width modulation (PWM) to achieve dimming. PWM works by pulsing the output current for a certain period of time (referred to as the duty cycle). At each pulse, the output current is increased or decreased in proportion to the duty cycle. By adjusting the duty cycle, the level of illumination of the LEDs can be controlled. The XRCWHT supports a 0-10V dimming signal, and the output current can be switched from its maximum level to a minimum level with a minimum dimming step.

In summary, the XRCWHT-L1-0000-00905 from ON Semiconductor is a highly efficient, controller-less LED driver optimized for non-dimmable and dim-to-warm white lighting applications. Its adaptive circuitry allows it to adapt to changing output conditions, and its Pulse Width Modulation (PWM) enables 0-10V dimming. The XRCWHT is ideal for a wide range of lighting applications, from linear fixtures to lamps, and offers excellent power factor, over-temperature protection, and high efficiency up to 90%.
