CAT4101
1 A Constant-Current LED
Driver with PWM Dimming
Description
high−brightness LEDs up to 1 A with very low dropout of 0.5 V 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 25 V, 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.
brightness adjustment by using an external pulse width modulation
(PWM) signal.
active whenever the die temperature exceeds 150°C.
