POWER Board
DC-DC
In electronic engineering, a DC to DC converter is an electronic circuit which converts a source of direct current (DC) from one voltage level to another. It is a class of power converter.
DC-DC converters accept a single direct current input, and convert it into very stable 3V, 5V and 12V lines that a Mini-ITX motherboard needs. The DC input will normally come from an external AC Adapter.
DC to DC converters are important in portable electronic devices such as cellular phones and laptop computers, which are supplied with power from batteries primarily. Such electronic devices often contain several sub-circuits, each with its own voltage level requirement different than that supplied by the battery or an external supply (sometimes higher or lower than the supply voltage, and possibly even negative voltage).
Additionally, the battery voltage declines as its stored power is drained.

Constant Current Regulator & LED Driver
The constant current regulator (CCR) is a simple, economical and robust device designed to provide a cost−effective solution for regulating current in LEDs. The CCR can be based on Self-Biased Transistor (SBT) technology and regulates current over a wide voltage range. It is designed with a negative temperature coefficient to protect LEDs from thermal runaway at extreme voltages and currents.

CCFL INVERTER
CCFL backlight inverters are used to provide power to the backlight of an LCD display. Still most of today´s displays use the technology of CCFL lamps in their backlight system. With modern backlight inverters the dimming range can be 100:1. This is close to a range of complete darkness up to full brightness. Backlight inverters supply a synthetic high voltage sine ware of 50 ~ 80 kHz to drive the CCFL lamp.
Next to the PCB’s we can provide the necessary cable kits.
