Description

The HVLED805TR is a electronic component model categorized as LED Drivers. It is a 600kHz constant frequency, voltage mode, synchronous PWM step down controller optimized for high efficiency. It is designed for split plane applications with a low power 5V rail to power the controller circuitry, minimizing power dissipation. The input voltage range is 3V to 15V, allowing for conversions from the standard 3.3V, 5V, 9.6V and 12V power rails to an output voltage adjustable down to 0.8V. The HVLED805TR is developed with a wide bandwidth internal amplifier that can accommodate type II and type III compensation schemes.
