PCA9633DEMO

The PCA9633DEMO evaluation board is a LED driver designed to enable a rapid evaluation of the PCA9633 4-channel LED driver and controller IC specifically designed for running RGB LEDs. This evaluation board also demonstrates how to easily interface the PCA9633 with an embedded processor using an I2C/SMBus compatible bus.

The PCA9633DEMO evaluation board is designed to help engineers evaluate the performance and features of the PCA9633. The board includes a PCA9633 IC, a prototyping area, a separate power supply terminal block, and a number of test points which allow the engineer to measure important functions.

The PCA9633DEMO works in both ‘full-speed’ and ‘dynamic’ modes, so the user can select the degree of dynamicity required for the specific application. The board also has an 18-pin expandable connector to allow the user to interface it directly to external electronics and/or an embedded processor.

The PCA9633DEMO is designed to provide all the features available in the PCA9633 IC. The board incorporates two independent 4-bit RGB-LED drivers that can be used to control either full color or individual RGB LEDs or any combination thereof. Each 4-bit driver supports 6-bit brightness control level and a 7-bit LED dimming level for driving individual LEDs.

The PCA9633DEMO supports a wide range of operating voltages from 1.8V to 3.6V. It also has in-built current and voltage protection features that allow the user to safely connect their development board and other external circuits. In addition to the 4-bit drivers, the board also incorporates a 3-bit safety register, allowing the user to set the safe current and voltage limits for the connected LEDs.

The PCA9633DEMO also provides a wide range of power supply options, including both AC and DC input, allowing the user to select the most suitable option for their application. The board also includes an on-board voltage regulator, allowing the user to efficiently supply power to the LEDs.

The PCA9633DEMO further supports an adjustable frequency range from 10kHz to 10MHz, providing the user with the flexibility to optimize current and voltage for a variety of driving conditions. The board also provides theuser with the capability to program the LED dimming level up to 256 steps, allowing the user to fine-tune the LED brightness for their specific application.

In addition to the features available on the PCA9633DEMO, the evaluation board also includes a 16-bit ADC that allows the user to measure a wide range of voltages in the range 0-3.3V. This enables the user to precisely measure the current and voltage levels of their LEDs.

Overall, the PCA9633DEMO evaluation board is a powerful and versatile LED driver and controller IC, designed to enable rapid prototyping and evaluation of the PCA9633 IC. The board provides the engineer with the flexibility to program, power and measure the output of LEDs in a single board solution.
