Description
The Lineage Power
®
Stingray™ Series, ESTW015A0F, Eighth-brick power modules are cost optimized isolated dc-dc
converters that can deliver up to 15A of output current and provide a precisely regulated output voltage over a wide range of
input voltages (Vin = 36 -75V
dc
). The module achieves full load efficiency of 91% at 3.3V
dc
output voltage. The open frame
modules construction, available in both surface-mount and through-hole packaging, enable designers to develop cost- and
space-efficient solutions. Standard features include remote On/Off, remote sense, output voltage adjustment, overvoltage,
overcurrent and overtemperature protection.

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 fast-acting fuse with a maximum rating of 5 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.

1. The module has an adaptable extended Turn-On Delay interval, T
delay
, of 25mS. The extended T
delay
will occur when the module restarts following
either: 1) the rapid cycling of Vin from normal levels to less than the Input Undervoltage Lockout (which causes module shutdown), 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
,
will occur whenever a module restarts with input voltage removed from the module for the preceding 1 second.
