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 (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
OUT
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
(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
