LP8556SQ-E08/NOPB General Description

The LP8556SQ-E08/NOPB is a highly advanced white-LED driver that incorporates an asynchronous boost converter and six precision current sinks. This versatile device can be controlled either by a PWM signal or an I2C master, offering flexibility and ease of use. Its adaptive output voltage control feature allows for optimal LED driver voltages ranging from 7V to 43V, resulting in minimal power consumption under all operating conditions. With three selectable switching frequencies and programmable slew rate control, the LP8556SQ-E08/NOPB ensures enhanced performance and reduced EMI

Key Features

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 V_DD 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 I²C 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
