Dual Output

Mixed Voltage, DLV Models

37 Watt, Isolated DC/DC Converters

OUT Combinations of 3.3/2.5/1.8/1.5 Volts

Murata’s new DLV Series, dual-output, low-voltage DC/DC’s provide any output

combination of 3.3V (to 6 Amps) and 2.5/1.8/1.5 (to 7 Amps). Designed with two

control loops for two independently regulated outputs (both using synchronous rec-

tiﬁcation), DLV’s are impressively efﬁcient (to 85%) and able to supply their full 13

Amps of output current (37W for the 3.3V/2.5V models) up to +60°C ambient with

no derating (model dependent).

Housed in standard 2" x 2" x 0.5" plastic packages, DLV’s offer a number of

functional options (positive or negative polarity on the control pin, addition of second

V^OUTtrim pin, etc.) that make them pin compatible with, yet more powerful than,

virtually all 2" x 2" duals from other leading DC/DC manufacturers.

Assembled using fully automated, SMT-on-pcb techniques, DLV’s provide

stable no-load operation, excellent line/load regulation ( 1%), quick step response

(200µsec), and low output ripple/noise (80mVp-p). All devices feature full I/O fault

protection including: input overvoltage and undervoltage shutdown, output overvolt-

age protection, current limiting, short-circuit protection, and thermal shutdown.

All DLV models are Qual/HALT/EMI tested and certiﬁed to the operational/func-

tional-insulation requirements of UL60950/EN60950. 48V^INmodels (75VIN max.)

carry the CE mark Selected models include RoHS-5 compliance with the lead

exception.
