Rarely, has a Series of low-power DC/DC converters been defined by both low

cost and DATEL's made-in-the-USA quality and reliability. Our new BST Series of

dual-output 3W DC/DC’s achieves this "best-of-both-worlds" status by implementing

a proven circuit architecture (170-200kHz flyback design) as a full, SMT-on-pcb

assembly (including surface-mount magnetics) that is truly 100% automatically

assembled. Packaged in miniature 1.25" x 0.8", DIP-like plastic packages (UL94V-0

rated) and requiring no external components, BST Series DC/DC’s bring true

component-like convenience to designers of today’s distributed power systems.

Output voltages are ±5, ±12 or ±15 Volts. Input voltage ranges are 4.5-9V

("D5" models), 9-18V ("D12" models) or an ultra-wide 18-72V ("D48" models). BST

DC/DC’s are fully isolated (1000Vdc guaranteed) and include input (pi type) and

output filters within their package. Output transient response is a quick 200µsec,

while output ripple and noise are typically 75mVp-p.

These rugged modules are fully encapsulated with a thermally conductive

potting compound that contributes to their outstanding moisture/vibration resistance

and impressive MTBF. They operate over the full –40 to +75°C temperature range

without derating. All models have been thoroughly characterized (electrically,

mechanically and thermally), qualified (including HALT), and EMI/EMC tested.

Additionally, they are certified to UL1950, CSA 22.2 No. 950 and IEC950.

DATEL’s BST Model 3W DC/DC’s are excellent selections for telecom/datacom,

computer and process-control applications demanding small size, low cost and high

reliability. If required, their design "flexibility" allows for easy modification to your

application-specific requirements.
