BCR430U

PG-SOT23-6

Description

BCR430U 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 100 mA connecting a high ohmic resistor Rset to pin RS. The maximum

voltage drop at the integrated LED driver stage is 200 mV at 50 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 BCR430U is

very high.

BCR430U

Low Voltage Drop LED Driver IC

Functional description

LED current configuration

The LED current is configured by the external resistor Rset at pin RS. The current flowing into pin LED is

proportional to the current flowing out of pin RS by a ratio of about 520:1. Therefore, the LED current depends

on the value of Rset.

BCR430U

Low Voltage Drop LED Driver IC

Functional description

Smart over temperature protection function

BCR430U reduces the LED current with increasing junction temperature by reducing the voltage at pin RS. The

reduced voltage of pin RS drives less current through the external resistor Rset, causing the current into pin LED

to reduce. The LED current is never turned oﬀ fully.
