Description
The EQW010/040 series DC-DC converters are designed to provide up to 40A output current in an industry
standard eighth brick package. These DC-DC converters operate over an input voltage range of 36 to 75 Vdc and
provide a single, precisely-regulated output. The output is isolated from the input, allowing versatile polarity
configurations and grounding connections. Built in filtering for both the input and output minimizes the need for
external filtering.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are
absolute stress ratings only, functional operation of the device is not implied at these or any other conditions in
excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for
extended periods can adversely affect the device reliability.

CAUTION: This power module is not internally fused. An input line fuse must always be used.
This power module can be used in a wide variety of applications, ranging from simple standalone operation to an
integrated part of sophisticated power architectures. To preserve maximum flexibility, internal fusing is not included,
however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies
require a time-delay fuse with a maximum rating of 8 A (see Safety Considerations section). Based on the
information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a
lower rating can be used. Refer to the fuse manufacturer’s data sheet for further information.

(B) device codes have an adaptable extended Turn-On Delay interval, T
delay
, as specified for B* devices. The extended T
delay
will occur
when a 12V
O
module restarts following either 1) the rapid cycling of Vin from normal levels to less than the Input Undervoltage Lockout and then back
to normal; or 2) toggling the on/off signal from on to off and back to on without removing the input voltage. The normal Turn-On Delay interval, T
delay
,
as specified for All Devices, will occur whenever a 12V
O
module restarts with input voltage removed from the module for the preceding 1 second.
