Working Principle

The MAX16807AUI+TG069 LED driver system operates on a switched-mode power conversion principle and is designed to deliver maximum efficiency. In this system, the input voltage is converted to a higher voltage (step up conversion) and then further converted to a lower voltage (step down conversion) to drive the LED for lighting. On the input side of the system, the input voltage is scaled up by a factor of 2 or 3 using an internal on-chip self-oscillating controller. The oscillator frequency is set to a fixed frequency (typically 1.5 MHz) which is higher than the audible range, so it doesn\'t cause any acoustic noise. The output voltage is then regulated to the desired level using a MOSFET switch with linear and hysteretic control loops. On the output side, the output voltage is fed back to the on-chip self-oscillating controller and regulated to the desired setpoint using a linear regulator. Additionally, the system offers over current protection, thermal regulation and other protection features. In short, the MAX16807AUI+TG069 operates on a switched-mode power conversion principle to efficiently drive high-power LEDs for lighting systems.
