- Enables flexibility in lighting applications and improves overall efficiency
- Includes a smart over-temperature controlling circuit for keeping the current constant at rising temperature
The voltage drop at the integrated driver IC can go down to 105 mV at 15 mA. This enables far more flexibility in lighting applications. It also improves the overall efficiency and provides the voltage headroom required to compensate for the LED forward voltage tolerances and variances in the supply voltage.
Provides ease of customising LED lights
The BRCU431U allows any number of additional LEDs to be added to lighting designs, for example, seven instead of six LEDs in series driven by one IC. Or it can be used to increase the overall length of a LED strip design from, for example, 5 to 7 m. Overall, longer LED strips mean fewer feeding points and fewer efforts in installation.
The LED current is easily adjustable via a high ohmic resistor on a dedicated pin with an IC supply voltage ranging between 6 V and 42 V. For safe and reliable operation and to extend the overall LED system’s lifetime, a smart over-temperature controlling circuit keeps the current constant even at rising temperature. At the same time, it reduces the LED current only when the junction temperature gets very high. The BCR431U features a dimming capability of down to 1 per cent, which makes it attractive for a great variety of LED strip designs.
The BCR431U can be ordered now in a SOT-23-6 package. In addition, a demo board is available.
