WHAT LED drive current?
LEDs are designed to run on low voltage (12-24V), direct current electricity. However, most places supply higher voltage (120-277V), alternating current electricity. An LED driver rectifies higher voltage, alternating current to low voltage, direct current.
Do LEDs regulate current?
LEDs are constant current devices with a forward voltage drop. This means the voltage supply must exceed that drop in order to allow current to flow, and by controlling the current, you control the intensity.
Which is a 16 bit constant current sink driver?
The STP16CPC26 is a monolithic, low voltage, 16-bit constant current LED sink driver. The device contains a 16-bit shift register and data latches, which convert serial input data into parallel output format. In the output stage sixteen regulated current generators provide 5 mA to 90 mA constant current to drive LEDs.
How does a 16 bit led sink work?
The device contains a 16-bit shift register and data latches, which convert serial input data into parallel output format. In the output stage sixteen regulated current generators provide 5 mA to 90 mA constant current to drive LEDs. The current is externally adjusted through a resistor.
Is the stp16cpc26 a 20 V drive?
The STP16CPC26 guarantees a 20 V driving capability, allowing users to connect more LEDs in series to each current source. The high 30 MHz clock frequency makes the device suitable for high data rate transmission. The thermal shutdown (170 °C with about 15 °C hysteresis) assures protection from overtemperature events.
