The CAT4101TV-T75 is a 1A constant-current LED Driver with PWM dimming. The constant-current sink driving a string of high-brightness LEDs up to 1A with very low dropout of 0.5V at full load. It requires no inductor, provides a low noise operation and minimizes the number of components. The LED current is set by an external resistor connected to the RSET pin. The LED pin is compatible with high voltage up to 25V, allowing the driving of long strings of LEDs. The device ensures an accurate and regulated current in the LEDs independent of supply and LED forward voltage variation. The PWM/EN input allows the device shutdown and the LED brightness adjustment by using an external pulse width modulation (PWM) signal.
● LED current set by external resistor
● High resolution PWM dimming via EN/PWM
● Zero current shutdown modes
● Thermal shutdown protection
