DATEL’s new DLV Series, dual-output, low-voltage DC/DC’s provide any output
combination of 3.3V (to 6 Amps) and 2.5/1.8/1.5/1.2V (to 7 Amps). Designed with
two control loops for two independently regulated outputs (both using synchronous
rectification), 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
VOUT trim 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
(200sec), 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/
functional-insulation requirements of UL60950/EN60950. 48VIN models (75VIN max.)
carry the CE mark
