MAX16820ATT+T Description

Short technical summary and product information.

The MAX16820ATT+T, manufactured by Analog Devices / Maxim Integrated, is a step-down constant-current high-brightness LED driver. It is suitable for applications such as architectural, industrial, and ambient lighting, as well as LED bulbs like MR16.

 

This device operates from a wide input voltage range of 4.5V to 28V and features a switching frequency up to 2MHz, enabling the use of small external components. It provides adjustable constant LED current with ±5% accuracy and includes a dedicated PWM input for a wide dimming range. The driver utilizes a hysteretic control algorithm for excellent input-supply rejection and fast transient response.

 

The MAX16820ATT+T is available in a compact 6-pin TDFN package measuring 3mm x 3mm x 0.8mm, making it ideal for space-constrained designs. It operates over an automotive temperature range of -40°C to +125°C.

 

Key features include high-side current sensing, adjustable constant LED current, and a 5V/10mA on-board regulator. The device is designed to minimize the number of external components, contributing to cost savings and simplified design.
