The SE8324 is a one switch, multi-topology LED controller that regulates LED current from input voltage above, below or equal to the output voltage. With 4.5V to 60V input, 0V to 60V output, and seamless low noise transitions between operation regions, the SE8324 is ideal for LED driver and battery charger applications in automotive, industrial and battery-powered systems.
The 60V capability coupled with the high-side current sense enables SE8324 to be used in a wide range of applications and drive in excess of 15 LEDs in series.
The special control scheme enables SE8324 to be dimming by both linear and PWM control signal.
Additional features include thermal shutdown, cycle-by-cycle current limit, output over voltage protection and over-current protection, soft start, smart thermal gradual protection, Internal Spread Spectrum Frequency Modulation for Low EMI.
The SE8324 is available in the DFN10 package.
