Description
The Bel SRDC-16D120 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 1.2V 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 3 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 3.0V 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 12.1K resistor and the pin’s logic
is active high.

RoHS Compliance
Complies with the European Directive 2002/95/EC, calling for the elimination of lead and other
hazardous substances from electronic products. These parts are not however compatible with
the higher temperatures associated with lead free solder processes and must be soldered
using a reflow profile with a peak temperature of no more than 240ºC.
