The Metamere Series offers a 50W power module in the

industry’s standard surface-mount footprint. The

Metamere series utilizes a low component count that

results in a low cost while still providing high performance.

The open-frame, compact design provides flexibility by

performing local voltage conversion of either a 5V or 3.3V

bus. The low weight, surface mount design is well suited

for almost any manufacturing environment.

Features

•Size - 33mm x 13.5 mm x 8.5 mm

(1.3 in. x 0.53 in. x 0.335 in.)

•Surface mountable

•Maximum weight 12g (0.42 oz)

•Up to 50W of output power in high

ambient temperature, low airflow

environments with minimal power

derating

•Positive logic on/off

•Starts with pre-biased output

•Output voltage adjustment

•Constant switching frequency

•Full, auto-recovery protection:

oInput under voltage

oShort circuit

oThermal limit

•Applying for UL 60950 (US and

Canada), VDE 0805, CB scheme

(IEC950) Safety markings
