[1] With Revision D forward of the WLD3343, an internal thermostat has been added to activate Shutdown (SHD) when the internal
temperature exceeds 105°C. The output will be re-enabled after a 250 to 300 ms slow-start once the internal temperature drops below
95°C.
[2] Bandwidth in Constant Power mode depends on photodiode bandwidth.
[3] Leakage current specification is based on full current set by R
Minimum turn-on current in the 200 mA range is 350 μA. Minimum turn-on current in the 2 A range is 12 mA. This specification applies to
Revision E forward.
Noise: To further reduce noise, the WLD3343-2L and WLD3343-3L models are available. Both are about 2.5 times lower
noise than the WLD3343 and WLD3343-3A, respectively. Constant Power (CP) mode is not available in these models.
