LD5850 Overview
The LD5850 is a wide-input asynchronous current mode boost controller, capable to operate in the range between 9V and 28V and to generate 14V of voltage to the GATE pin of MOSFET to reduce thermal loss. The current mode control architecture enhances transient response and simplifies the loop pensation. The DIM input allows the brightness control for LED Backlight or LED lighting.
