Evaluation Boards - LED Drivers: CRD1616A-9W-Z

CRD1616A-9W-Z is one of the most versatile and popular evaluation boards for LED drivers. It is widely used in both high-power and low-power LED applications, as it can provide both dimmable and non-dimmable control in a highly efficient, space-saving design.

The advanced LED driver IC - the chip used powering the CRD1616A-9W-Z is a CRD1616A-9W (External MOSFET). The driver IC is designed with a wide input voltage range, allowing it to be compatible with both AC and DC power sources. This makes it ideal for use in both indoor and outdoor applications, as well as industrial and commercial lighting systems.

The CRD1616A-9W also features adjustable operating frequency, which increases power efficiency and improves the lifespan of the LEDs. The adjustable operating frequency also has a positive effect on the ripple current, reducing its impact on the driver IC.

The CRD1616A-9W-Z is a non-isolated buck-boost converter. It is capable of providing a constant output voltage over a wide range of input voltages, allowing it to maintain consistent performance during large input voltage fluctuations. This eliminates the need for additional capacitors or voltage justment components.

The CRD1616A-9W-Z also features built-in over-temperature protection and short-circuit protection. These two features, combined with its high efficiency, make it ideal for high-power applications as it helps protect against damage and power losses.

The CRD1616A-9W-Z works by controlling an external MOSFET which is used to regulate the output voltage according to the commanded values. This is done by switching the MOSFET on and off at a frequency determined by an internal clock. The chip also has a clock output pin which allows a microcontroller to adjust the frequency according to the required output voltage.

The CRD1616A-9W-Z also features a dimming and intensity control pin, which allows it to be used for light intensity control in applications such as LED modules or spotlighting. The integrated dimming and intensity control pin can be programmed to provide adjustable intensity, from 0% to 100%, eliminating the need for additional opto-couplers or isolators.

Overall, the CRD1616A-9W-Z is an ideal choice for both high- and low-power LED applications. Its adjustable frequency and wide input voltage range make it highly compatible with both AC and DC power sources. The built-in over-temperature protection and short-circuit protection make it suitable for use in high-power applications, while the adjustable intensity control provides smoother brightness control for indoor applications. The CRD1616A-9W-Z is an excellent choice for LED drivers.
