Notes:
[1]    In the WLD3343 and WLD3343-2L models, internal power dissipation is 1.2 W (without heatsink), 2 W (with 
heatsink), and 9 W (with heatsink and fan).  In the WLD3343-3A and WLD3343-3L models, internal power dissipation 
is 2 W (without heatsink), 3 W (with heatsink), and 10 W (with heatsink and fan).
[2]   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 msec slow-start once 

the internal temperature drops below 95

˚

C.

[3]   Max ambient operating temperature of the WLD3343-3A and WLD3343-3L is 45°C.
[4]   Leakage current speci

fi

 cation is based on full current set by R

SENSE

.  See page 9 for information on setting the 

current range.  Minimum turn on current in the 200 mA range is 350 

μ

A.  Minimum turn on current in the 2 A range is 

12 mA.  This speci

fi

 cation applies to Rev. 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.
