High Power LED Driver with Pre-Emptive Boost for Ultra-High Dimming Ratio and Low Output Ripple

The A80601 is a multi-output LED driver for automotive applications such as exterior lighting, heads-up display, and mid-size LCD backlighting. It implements a current-mode boost/ SEPIC converter with gate driver for external N-MOSFET. This allows greater output power even at minimum supply voltage. \n? Enhanced fault handling for ASIL B system compliance\n? Operate in Boost or SEPIC mode for flexible output\n? Four integrated LED current sinks, up to 210 mA each\n? Programmable boost frequency dithering to reduce EMI\n? LED contrast ratio: 15,000:1 at 200 Hz using PWM dimming alone, 150,000:1 ;
