MAX16820ATT+T - Maxim Integrated Function Overview

The MAX16820ATT+T is a 2MHz high brightness LED driver with high-side current sense and 5000:1 dimming in 6 pin TDFN package. It is a step down constant current high brightness LED (HB LED) drivers provides a cost-effective solution for architectural and ambient lighting, LED bulbs such as MR16 and other LED illumination applications. It operates from a 4.5V to 28V input voltage range and has 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 high-side current sensing and an integrated current-setting circuitry minimize the number of external components while delivering an LED current with ±5% accuracy. A hysteretic control algorithm ensures excellent input supply rejection and fast response during load transients and PWM dimming. The MAX16820 features a 10% current ripple. This device operates up to 2MHz switching frequency, thus allowing for small component size.
