O2Micro Unveils OZ8022VM LED Driver Controller

O2Micro International (News - Alert) Limited has unveiled the OZ8022VM LED Driver Controller, further enhancing its General Lighting product group. The huge volume, non-dimming luminescent bulb replacement market, comprising of PAR lamps, A bulbs and BR bulbs, will find this latest offering ideal.

A solitary LED bulb incorporating the OZ8022VM, which supports worldwide 85V to 265V operation, can now be used across the international marketplace. Apart from decreasing SKUs, the OZ8022VM augments operational effectiveness due to economy of scale.

Steady lumen output across the world, irrespective of the changing line input environment, is possible due to the first-class LED current guideline and precision over the complete widespread input range.

An in-built, high voltage power MOSFET is incorporated by the OZ8022VM, resulting in an affordable, small footprint, 8-pin SOP package. An extremely low BOM count and the total lowest expense at the system BOM level are possible with this finest incorporation.

The incorporation also offers a compact design, ideal for space-confined applications.

High-power factor, greater than 0.9 for the general 85-265V input range along with low THD, which is less than 20 percent, is possible with the incorporated power factor correction. Bulbs which make use of the OZ8022VM can therefore adhere to the international residential and commercial needs and rules – like EPA Energy Star.

Best-in-class effectiveness of at least 88 percent is ensured across the complete universal voltage range, resulting in decreased energy usage and simplified thermal administration. Minimum off-time control offers the best possible operating effectiveness during light load settings.

The best possible conversion competence is also ensured due to low startup and operation currents.

Non-isolated buck converter applications, which make use of quasi-resonant conversion technology, will find the OZ8022VM ideal. End-user requirements are addressed by the speedy turn-on of the OZ8022VM, which also features incorporated over-temperature, over-voltage, cycle-by-cycle current restrictive, LED open circuit and LED short circuit protection – with auto-recovery, delivering a secure and dependable operation.

Power management units, ideal for the Computer, Consumer, Industrial, Automotive and Communications markets, are developed and promoted by O2Micro. These include LED General Lighting, Backlighting, Battery Management and Power Management.

O2Micro was established in April of 1995 and has offices in the United States, Cayman Islands, Taiwan, Japan, China and Korea.
