A80604 and A80604-1
High Power LED Driver with Pre-Emptive Boost for Ultra-High Dimming Ratio and Low Output Ripple
FEATURES AND BENEFITS
• Automotive AEC-Q100 qualified • Enhanced fault handling for ASIL B system compliance • 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 • Four integrated LED current sinks, up to 210 mA each • Boost switching frequency synced externally or
programmed from 260 kHz to 2.3 MHz • Programmable boost frequency dithering to reduce EMI • Advanced control allows minimum PWM on-time down
to 0.
