LC101N
Data Sheet
Description
LC101N is a current control IC that uses a low-saturated PNP bipolar transistor in the power block. The saturation
voltage of the saturated condition is small and can be designed with minimal losses in the case of driving with a constant current source. The constant current value is set up by the resistor connected between the FB terminal and the LO pin, and you can drive the LED in the constant current condition. LC101N is available in an 8-pin DFN package for surface mounting.
Features
● Maximum current is 150 mA ● Low input-output
voltage difference design is
achieved by low saturation
voltage; VDIF(max.)=0.35 V (Io = 150 mA) ● Reference
voltage of 200 mV reduces the sense resistor loss ● Optimal balance operation can be realise in parallel connection of multiple LED strings ● Protections Overcurrent Protection (OCP): Foldback Thermal Shutdown (TSD): Auto-restart
