MAX16812 Integrated High-Voltage LED Driver With Analog And PWM Dimming Control

The MAX16812 is a peak-current-mode LED Driver with an integrated 0.2 Power MOSFET designed to control the current in a single string of high-brightness LEDs (HB LEDs). The MAX16812 CAN be used in multiple converter topologies such as buck, boost, or buck-boost. The MAX16812 operates over a 5.5V to 76V wide supply voltage range.
The MAX16812 features a low-frequency, wide-range brightness adjustment (100:1), Analog and PWM dimming control input, as well as a resistor-programmable EMI suppression circuitry to control the rise and fall times of the internal switching MOSFET A high-side LED current-sense Amplifier and a dimming MOSFET driver are also included, simplifying the design and reducing the total component count.
The MAX16812 uses peak-current-mode control, adjustable slope compensation that allows for additional design flexibility. The device has two current regulation loops. The first loop controls the internal switching MOSFET peak current, while the second current regulation loop controls the LED current. Switching frequency CAN be adjusted from 125kHz to 500kHz.
Additional features include adjustable UVLO, soft-start, external enable/disable input, thermal shutdown, a 1.238V 1% accurate buffered reference, and an on-chip Oscillator An internal 5.2V linear Regulator supplies up to 20mA to power external devices.
The MAX16812 is available in a thermally enhanced 5mm x 5mm, 28-pin TQFN-EP package and is specified over the automotive -40C to +125C temperature range.
