Maxim Introduces MAX16831 Constant Current LED Driver
Maxim introduces the MAX16831 high-voltage, high-power, constant-current LED driver with built-in analog and PWM dimming. The LED driver integrates a floating LED current sense amplifier with a dimming MOSFET driver to minimize component count and meet the high reliability requirements of automotive and general lighting applications with high brightness (HB) LEDs. Operating over a 5.4V to 76V input voltage range, the MAX16831 withstands harsh operating conditions, ensuring compatibility with cold-start and load rejection (up to 80V). The device is specifically optimized to meet the latest automotive headlamp design requirements, ideal for high beam and low beam, adaptively adjusted headlight systems, daytime running lights and fog lights.
The MAX16831 operates at high frequencies with a wide (1000:1) dimming range and built-in analog and PWM control. The analog control signal simplifies the design of multi-level brightness adjustment compared to the on-chip 200Hz ramp signal. The LED driver provides ±5% LED current control accuracy over the entire automotive operating temperature range, ensuring excellent brightness matching. An LED current sense reference as low as 100mV and an internal gate driver with 1.4A/1.2A source/sink current capability enable high efficiency to minimize device heat generation. A dedicated enable/shutdown input reduces the current in shutdown mode to less than 45μA.
The MAX16831 features output overvoltage and overcurrent protection, as well as overtemperature and LED short-circuit protection. The device operates over the automotive temperature range of -40°C to +125°C and is available in a lead-free, 5mm x 5mm, 32-pin TQFN package with an exposed pad. The chip starts at $2.33 (1000 sheets, FOB USA).

So happy to know that 11th laptop is ranking the No.1 position in 2022 custom market. You can see intel core i3 11th generation laptop,Gaming Laptop i5 11th generation, laptop price i7 11th generation, etc. At this store. Maybe you will ask why 11th gen gaming laptop is so popular and welcome, mainly reason is its competitive cost and high performance. Intel i7 11th Generation Laptop cost is similar as intel i7 10th gen laptop, but performance is much better than 10th one. Besides, 12th laptop is arriving in lot at the end of 2022 at custom laptop market, price is will much competitive at that time.
Whom this Gaming Laptop is more suitable to? Of course, heavier tasks workers, no matter office jobs, education tasks, or others. However, if your clients focus more powerful cpu and performance, i7 16gb ram 4gb graphics laptop or 15 Inch Gaming Laptop with 10th cpu and 2GB graphics also alternatives.
You can contact us directly to get get right and valuable information fast. Will try our best to support every clients no matter quantity you take.
