BCR431U Low Voltage Drop LED Driver IC Features
• Supply voltage from 6 V to 42 V • Controls up to 36.5 mA LED current • Max. 200 mV saturation voltage at 32.8 mA • LED current precision ±10 % • Smart over temperature protection function
Advantages with respect to discrete solutions
• Low BOM count • Lower assembly cost • Smaller form factor • Higher reliability due to less parts and soldering joints
Potential Applications
• LED strips • LED displays and channel letters • Architectural and landscape lighting • Retail lighting
Product Validation
• Qualified for industrial applications according to the relevant tests of JEDEC47/20/22
Product Name Package
BCR431U PG-SOT23-6
Description
BCR431U is a linear LED driver IC in a small PG-SOT23-6 package regulating the LED current in standalone operation without any external power transistor. The IC supply voltage range is from 6 V up to 42 V. The LED current level can be adjusted up to 36.5 mA connecting a high ohmic resistor Rset to pin RS. The maximum voltage drop at the integrated LED driver stage is 200 mV at 32.8 mA improving the overall system efficiency and providing extra voltage headroom to compensate for tolerances of LED forward voltage or supply voltage. The smart over temperature protection function reduces the LED current when junction temperature of BCR431U is very high.
