4-Channel Quad-Mode
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.
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.
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.
accommodate dimming frequencies in excess of 10 kHz thereby
providing extremely high resolution brightness levels.
