CAT4238AGEVB: High Voltage CMOS Constant-Current DC-DC Converter Evaluation Board


The CAT4238 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 10 white LEDs in series. A single external resistor sets the LED current between 5mA and 40 mA. LED current can be adjusted using either a pulse width modulated (PWM) signal or a DC voltage.
