CAT3604V/D

CAT3604V

Driver with Open/Short LED

Detection

Description

pump that can drive up to four LEDs with input supply voltages as low

as 2.5 V.

An external RSET resistor is used to control the LED channel

brightness while channel diagnostics include automatic detection for

both short and open LED channel conditions, ensuring the CAT3604V

maintains the highest efficiency level in all operating modes.

Each operating mode uses a constant high frequency switching

scheme which allows the use of small form factor external ceramic

capacitors while delivering excellent low noise input supply ripple up

to 5.5 volts.

The EN input control supports direct PWM dimming and can

accommodate dimming frequencies in excess of 10 kHz thereby

providing extremely high resolution brightness levels.

The device is available in the 16−pad low profile 0.8 mm thin QFN

(4 mm x 4 mm).
