NON-ISOLATED DC/DC CONVERTERS
BP06SRDC-16D180
3 15V Input / 1.8V Output / 16A
Description
The Bel SRDC-16D180 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 1.8V 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.

3 15V Input / 1.8V Output / 16A

Input Specifications
Absolute Maximum Ratings
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.
Note: Input capacitance 100F/16V, ESR = 0.03
max at 100kHz @ 25 C.
1. With simulated source impedance of 500nH, 5Hz to 20MHz.
2. UVLO is adjustable by terminating on/off pin to ground per the termination resistance table
on page 7.
