MAX25601BAUI/V+

MAX25601B is a synchronous boost and synchronous buck LED controller. The 4.5V to 40V input voltage range of the boost controller ideal for automotive applications, and acts as a pre-boost power supply for the second-stage buck LED controller. The synchronous boost is a current-mode controller that can be paralleled with another device to provide higher output power. A SYNCOUT pin provides the clock to drive the RT/SYNCIN pin of the other device, enabling two-phase 180-degree out-of-phase operation. Spread spectrum is included to reduce EMI. Application includes automotive exterior lighting high-beam/low beam/ signal/position lights, daytime running lights (DRLs), matrix light, pixel light, and other adaptive front-light assemblies, commercial, industrial, and architectural lighting.

• No HUD driver feature, 36V feature
• Integration minimizes BOM for high-brightness LED driver, saving space and cost
• Wide boost-output range up to 65V, programmable switching frequency optimizes component size
• External MOSFETs can be sized for appropriate current
• Synchronous rectification provides high efficiency and fast transient response
• Average current-mode control for buck eliminates compensation components
• Wide dimming ratio allows high contrast ratio
• Analog dimming and PWM dimming, analogue voltage-controlled PWM dimming
• Short circuit, overvoltage, and thermal protection
• 28 TSSOP-EP package, operating temperature range from -40°C to 125°C
