MAX1583EVKIT

The MAX1583EVKIT is a fully assembled and tested surface-mount circuit board for evaluating the MAX1583EVKIT white LED flash boost converter. The EV kit accepts a 2.6V to 5.5V input voltage and drives up to five series white LEDs with a constant current to provide camera flash/strobe in cell phones, PDAs, DSCs,and other hand-held devices.

Features of the MAX1583EVKIT are:(1)supports up to 5 leds for strobe/flash;(2)four operational modesstrobe: up to 300ma (preset to 100ma) precharge: with pok indicator movie: up to 100ma (preset to 20ma) shutdown: 0.01a (typ) quiescent current;(3)input current limiting;(4)24v output overvoltage protection;(5)80% efficient (pled / pin) movie mode;(6)thermal-shutdown protection;(7)10-lead 3mm x 3mm tdfn package;(8)surface-mount components;(9)fully assembled and tested.

The JU1 and JU2 functions (dimming control) of the MAX1583EVKIT can be summarized as:(1):the JU2 position is 1 and 2,the EN1 is connected to VIN,the JU1 position is 1 and 2,the EN2 is connected to VIN,the output is strobe mode;(2):the JU2 position is 1 and 2,the EN1 is connected to VIN,the JU1 position is 2 and 3,the EN2 is connected to GND,the output is movie mode;(3):the JU2 position is 2 and 3,the EN1 is connected to GND,the JU1 position is 1 and 2,the EN2 is connected to VIN,the output is precharge mode;(4):the JU2 position is 2 and 3,the EN1 is connected to GND,the JU1 position is 1 and 2,the EN2 is connected to GND,the output is shutdown mode.
