Description
The Bel S7DC-16D330 module is one in a series of non-isolated, DC/DC power converters that operate from a wide input
range of 3V minimum to 15V maximum. This converter is available with 3.3V output. It uses a low profile, surface mount DIP
package for ease of layout and space savings. 16A maximum output is also provided. Standard features include remote
on/off, over current and short circuit protection, programmable UVLO and output voltage adjust. Optional features include
two-wire remote sense or single-ended remote sense with a good power signal. This module also makes use of adaptive
positioning to improve transient response performance. It may be used almost anywhere low voltage silicon is employed
and a 4.75 to 15V source is available. Typical applications include file servers, routers, line cards and other computing and
communications equipment.

Note: Use beyond the maximum ratings may cause a reliability degradation of the DC/DC
converter or may permanently damage the device.
1. The enable pin performs two functions, remote on/off and programmable under voltage
lockout. The factory set UVLO point is 4.25V typical, but can be adjusted upward with
the addition of a single external resistor located from the enable pin to ground. Turning
the converter on and off is accomplished using an open collector/drain device as a
switch. The enable pin is internally pulled up to Vin through a 11.5K resistor and the
pin’s logic is active high.
