*Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device.
These are stress ratings only, which do not imply functional operation of the device at these or any other
conditions beyond those indicated under recommended operating conditions. Exposure to absolute-maximum-
rated conditions for extended periods may affect device reliability.

3. Description

The SF6040 is a non-isolated DC/DC SMPS
(POL) with constant current output. Driver
produces high stability and low ripple
current. Protection features include an over
current protection with adjustable limit, soft-
start, thermal warning and shutdown,
reverse current protection and crowbar
circuit protection. This means the SF6040 can
safely drive nonlinear and current quality
sensitive loads like laser diodes and LEDs.
The driver can be controlled by analogue
or digital signals.
SF6040 is available in thermal enhanced
quarter-brick package with aluminum base
plate to aid thermal dissipation. Driver can be
mounted on any thermal conductive surface
enough to dissipate driver losses.
