MAX16833B - High-Voltage HB LED Drivers

This page provides the datasheet information for the MAX16833B, a member of the MAX16833 High-Voltage HB LED Drivers family.

Datasheet Summary

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.

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.

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. This feature provides extremely fast PWM current switching to the LEDs with no transient overvoltage or undervoltage conditions. In addition to PWM dimming, the ICs provide analog dimming using a DC input at ICTRL. The ICs sense the LED current at the high side of the LED string.
