Maxim IC MAX16819 2MHz High-Brightness LED Drivers

Maxim Integrated MAX16819 2MHz HB LED Drivers

Maxim Integrated MAX16819 2MHz high-brightness LED (HB LED) drivers provide high-side current sense and 5000:1 dimming and are a cost-effective solution for automotive interior/exterior lighting, architectural and ambient lighting, LED bulbs such as MR16, and LED illumination applications. Maxim Integrated MAX16819 HB LED drivers operate from a 4.5V to 28V input voltage range and feature a 5V/10mA on-board regulator. A high-side current-sense resistor adjusts the output current and a dedicated PWM input (DIM) enables a wide range of pulsed dimming. The Maxim Integrated MAX16819 features high-side current sensing and integrated current-setting circuitry for reduced external component count while delivering an LED current with ±5% accuracy.
