CAT3604V/D
CAT3604V
4-Channel LED Driver with
Open/Short LED Detection
Description
The CAT3604V is a high efficiency fractional charge 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 V.
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 16pad low profile 0.8 mm thin QFN
(4 mm x 4 mm).
