PRODUCT OVERVIEW
ꢀ
Regulated Intermediate Bus Architecture (RIBA)
The DRQ-8/100-L48NB-C regulated converter
module deliver a 8.0V output @ Vin = 48Vdc in a
quarter brick open frame package at astonishing
efficiency. The fully isolated (1500Vdc) DRQ-
8/100-L48NBxxxx-C series accept a 36 to 60 Volt
DC input voltage range and converts it to a low
Vdc output that drives external point-of-load (PoL)
DC-DC power converters such as Murata Power
Solutions’ tiny Okami series which feature precise
regulation directly at the load. Applications include
datacom and telecom installations, cellular data-
phone repeaters, base stations, instruments and
embedded systems. Wideband output ripple and
noise is a low 100mV, peak-to-peak.
The DRQ’s synchronous-rectifier topology and
fixed frequency operations means excellent effi-
ciencies up to 95.8 %.
ꢀ
95.8% ultra-high efficiency at full load
ꢀ
36V-60V DC input range (48V nominal)
A wealth of electronic protection features include
input under voltage lockout, over voltage lockout
protection, output current limit, current sharing,
short circuit hiccup, Vout overshoot, and over
temperature shutdown. Available options include
various pin lengths and the baseplate. Assembled
using ISO-certified automated surface-mount
techniques, the DRQ series is designed to meet
all UL and IEC emissions, safety and flammability
certifications.

A Single Output Pins Version is availabe where Pin 4 and Pin 8 are removed. The
option (A) allows customers to upgrade the power in applications where the Dual
Pin would require layout cha nges. See the specific mechanical drawings and
performance data.
