A80605-1
FEATURES
AND BENEFITS
- Automotive AEC-Q100 qualified
- Enhanced fault handling for ASIL B system pliance
- Wide input voltage range of 4.5 to 40 V for start/stop, cold crank, and load dump requirements
- Operate in Boost or SEPIC mode for flexible output
- Gate driver for external MOSFET to deliver higher output power
- Six integrated LED current sinks, up to 140 m A each
- Boost switching frequency synced externally or programmed from 260 k Hz to 2.3 MHz
- Programmable boost frequency dithering to reduce EMI
- Advanced control allows minimum PWM on-time down to 0.3 µs, and avoids MLCC audible noises
- LED contrast ratio: 15,000:1 at 200 Hz using PWM dimming alone, 150,000:1 when bining PWM and analog dimming
