MAX16833 Datasheet High-Voltage HB LED Drivers

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: MAX16833/MAX16833B/C/D/G EVALUATION KIT AVAILABLE High-Voltage HB LED Drivers with Integrated High-Side Current Sense.

General Description

The MAX16833, MAX16833B, MAX16833C, MAX16833D, and MAX16833G are peak current-mode-controlled LED drivers for boost, buck-boost, SEPIC, flyback, and highside buck topologies.

A dimming driver designed to drive an external p-channel in series with the LED string provides wide-range dimming control.

Key Features

  • include a fault-indicator output (FLT) for short or overtemperature conditions and an overvoltage-protection sense input (OVP) for overvoltage protection. High-side current sensing combined with a p-channel dimming MOSFET allow the positive terminal of the LED string to be shorted to the positive input terminal or to the negative input terminal without any damage. This is a unique feature of the ICs.
