CAT3224 driver equivalent, 4 amp supercapacitor flash led driver.
two matched current sources. External resistors provide the adjustment for the maximum flash mode current (up to 4 A) and the torch mode current (up to 400 mA). A built−i.
Ideal for Li−ion battery−powered systems, it delivers up to 4 A LED flash pulses, far beyond the peak current capabilit.
The CAT3224 is a very high−current integrated flash LED driver which also supports the charging function for a dual−cell supercapacitor applications. Ideal for Li−ion battery−powered systems, it delivers up to 4 A LED flash pulses, far beyond the pea.
