LP8556SQE-E00/NOPB TI
• High-efficiency DC/DC boost converter with integrated 0.19-Ω power MOSFET and three switching frequency options: 312 kHz, 625 kHz, and 1250 kHz
• 2.7-V to 36-V Boost switch input voltage range supports multi-cell Li-Ion batteries (2.7-V to 20-V VDD input range)
• 7-V to 43-V Boost switch output voltage range supports as few as 3 WLEDs in series per channel and as many as 12
• Configurable channel count (1 to 6)
• Up to 50 mA per channel
• PWM and / or I 2C brightness control
• Phase-shift PWM mode reduces audible noise
• Adaptive dimming for higher LED drive optical efficiency
• Programmable edge-rate control and spread spectrum scheme minimize switching noise and improve EMI performance
• LED fault (short and open) detection, UVLO, TSD, OCP, and OVP (up to 6 threshold options)
• Available in tiny 20-pin, 0.4-mm pitch DSBGA package and 24-pin, 0.5-mm pitch WQFN package
