The Belleta Series offers a 35W PicoBrick power module in the

industry’s smallest 10A footprint that is 33% smaller than an

industry standard eighth brick and power pin compatible with an

existing industry standard footprint. The Belleta Series eliminates

the need to use highly derated eighth or quarter brick power

modules, thereby optimizing board space utilization and cost. As

with other modules in the Belleta series, a low component count

results in a low cost, high performance design. The low weight,

surface mount design is well suited for almost any manufacturing

environment.

Features

• Size - 30.5mm x 29.3 mm x 8.1 mm

(1.20 in. x 1.16 in. x 0.32 in.)

• Surface mountable

• Maximum weight 18g (0.65 oz)

• Up to 35W of output power in high

ambient temperature, low airflow

environments with minimal power

derating

• Basic insulation – 1500Vdc

• Negative logic on/off

• Monotonic start-up

• Starts with pre-biased output

• Output voltage adjustment

• Constant switching frequency

• Full, auto-recovery protection:

o Input under voltage

o Output over voltage

o Current limit

o Short circuit

o Thermal limit

• Applying for UL 60950 (US and

Canada), VDE 0805, CB scheme

(IEC950) Safety markings

• CE Mark (EN60950) pending

• Multiple patents pending
