High-Voltage, High-Power LED Driver with Analog and PWM Dimming Control
General Description
The MAX16831 is a current-mode, high-brightness LED (HBLED) driver designed to control two external n-channel MOSFETs for the single-string LED current regulation.
The MAX16831 integrates all the building blocks necessary to implement fixed-frequency HBLED drivers with wide-range dimming control.
The MAX16831 is configurable to operate as a step-down (buck), step-up (boost), or step-up/-down (buck-boost) current
regulator.
Current-mode control with leading-edge blanking simplifies control-loop design.
Internal slope compensation stabilizes the current loop when operating at duty ...
