High-Voltage HB LED Drivers with

Integrated High-Side Current Sense

General Description

Features

S Boost, SEPIC, and Buck-Boost Single-Channel

The MAX16833/MAX16833B/MAX16833C/MAX16833D/

MAX16833E are peak current-mode-controlled LED driv-

ers for boost, buck-boost, SEPIC, flyback, and high-side

buck topologies. A dimming driver designed to drive

an external p-channel in series with the LED string pro-

vides 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 dim-

ming using a DC input at ICTRL. The ICs sense the LED

current at the high side of the LED string.

LED Drivers

S +5V to +65V Wide Input Voltage Range with a

Maximum 65V Boost Output

S Integrated High-Side Current-Sense Amplifier

S ICTRL Pin for Analog Dimming

S Integrated High-Side pMOS Dimming MOSFET

Driver (Allows Single-Wire Connection to LEDs)

S Programmable Operating Frequency (100kHz to

1MHz) with Synchronization Capability

S Frequency Dithering for Spread-Spectrum

Applications (MAX16833/MAX16833C/MAX16833E)

A single resistor from RT/SYNC to ground sets the

switching frequency from 100kHz to 1MHz, while an

external clock signal capacitively coupled to RT/SYNC

allows the ICs to synchronize to an external clock. In

the MAX16833/MAX16833C/MAX16833E, the switching

frequency can be dithered for spread-spectrum applica-

tions. The MAX16833B/MAX16833D instead provide a

1.64V reference voltage with a 2% tolerance.

S 2% Accurate 1.64V Reference (MAX16833B/

MAX16833D)

S Full-Scale, High-Side, Current-Sense Voltage of

200mV

S Short-Circuit, Overvoltage, and Thermal

Protection

S Fault Indicator Output

S -40NC to +125NC Operating Temperature Range

The ICs operate over a wide 5V to 65V supply range

and include a 3A sink/source gate driver for driving

a power MOSFET in high-power LED driver applica-

tions. Additional 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 termi-

nal or to the negative input terminal without any damage.

This is a unique feature of the ICs.
