Description
   The CAT3604V is a high efficiency Quad−Mode® 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.
