The MAX16819/MAX16820 series, including the MAX16820ATT+T, are step-down constant-current high-brightness LED drivers designed for architectural, ambient lighting, and LED bulb applications. They provide a cost-effective solution with accurate LED current control.
These drivers operate from a wide 4.5V to 28V input voltage range and feature a 5V/10mA on-board regulator. The MAX16820ATT+T utilizes a high-side current-sense resistor to adjust output current and a dedicated PWM input for pulsed dimming, enabling a wide dimming range of 5000:1. The hysteretic control algorithm ensures excellent input-supply rejection and fast response during load transients.
With a switching frequency up to 2MHz, these devices allow for small component sizes. The MAX16820ATT+T delivers ±5% LED current accuracy and is suitable for applications requiring over 25W output power. It operates within an automotive temperature range of -40°C to +125°C.
The MAX16820ATT+T is available in a compact 6-pin TDFN-EP package, measuring 3mm x 3mm x 0.8mm, designed for surface mounting. This package type, combined with the integrated circuitry, minimizes the number of external components, saving space and cost in designs.
