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 onchip oscillator. An internal 5.2V linear regulator supplies up to 20mA to power external devices.
