Figure 1. Simplified Schematic

Featuring DATEL’s ultra-wide, 18-72V , input v oltage range, this new F amily 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 1.8 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 lo w cost
and outstanding long-term reliability. Their design combines straightforw ard circuit
topologies, proven SMT-on-pcb construction methods, the newest components, and
highly repeatable automatic-assembly techniques. The A-Series TWR’ s superior
durability is substantiated by a rigorous in-house qualification program that includes
HAL T (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-conductive
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.
