Figure 1. Simplied Schematic
Featuring DATEL’s ultra-wide, 18-72V, input voltage range, this new Family of
A-Series, TWR (triple-output) DC/DC converters deliver up to 15 Watts. These
devices each have a primary +5V output that can source from 1 Amp to 1.5 Amps
(model dependent) and auxiliary ±12/15V outputs that can source from ±150 to
±250mA (model dependent). All models can simultaneously source maximum
rated current from both primary and auxiliary outputs. The nominal input voltage
for each model is 48V.
As members of DATEL’s new A-Series, the 12-15W triples exhibit both low cost
and outstanding long-term reliability. Their design combines straightforward circuit
topologies, proven SMT-on-pcb construction methods, the newest components,
and highly repeatable automatic-assembly techniques. The A-Series TWR’s supe-
rior durability is substantiated by a rigorous in-house qualication program that
includes HALT (Highly-Accelerated Life Testing), which is designed to detect any
potential electrical, mechanical or process weakness.
Packaged in standard, 2" x 2" x 0.45", shielded metal cases with non-conduc-
tive coatings, these fully isolated (1000Vdc minimum) DC/DC’s offer excellent line
and load regulation. Additionally, these A-Series triples have non-latching output
current limiting, input overvoltage shutdown, input reverse-polarity protection, and
output overvoltage clamping to protect both the power converters and their loads.
All A-Series TWR models are fully EMI characterized and designed to meet
UL1950, IEC 950, CSA 950 and EN60950.
