CAT4237BGEVB: High Voltage CMOS Constant-Current DC-DC Converter Evaluation Board


The CAT4237 is a high voltage CMOS constant-current DC/DC converter that has been designed to drive with high efficiency white or other high brightness LEDs. The high-voltage output stage allows driving up to 8 white LEDs in series. A single external resistor sets the LED current between 5mA and 30mA. LED current can be adjusted using either a pulse width modulated (PWM) signal or a DC voltage. Detailed descriptions and electrical characteristics are in the CAT4237 data sheet. The evaluation board contains a CAT4237 DC-DC boost converter and an array of white LEDs. As configured, the board circuit is set to drive up to 8 white LEDs in series. The user can chose to connect the CAT4237 output to the LEDs string available on board or to an external LEDs string from an application.
