Beschreibung
This application note describes a driver solution developed using the Zetex ZXLD1362 LED driver IC for an automotive EMC compliant solution. ZXLD1362 switching regulator allows to maximize the efficiency gains offered by LED lighting solutions in automotive applications, while reducingthe component count and the complexity of the circuit.
Eigenschaften
- Wide input voltage range
- 7V to 60V; internal 60V NDMOS switch
- Up to 1A output current
- Capable of driving up to 16 series connected 3 Watt LEDs
- High efficiency (see datasheet - but >90% with 15 LEDs)
- Low quiescent current: (100uA typical)
- Brightness control using DC voltage or PWM (low or highfrequency)
- Optional soft-start; up to 1MHz switching frequency
