04/01/2013
Boost Controller for LED Backlight
REV: 00
General Description
The LD5861 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 compensation. The DIM input allows the brightness control for LED Backlight or LED lighting.
The Device also features internal slope compensation, input voltage under-voltage lockout, output voltage short circuit protection, cycle-by-cycle current limit and thermal shutdown protection.
Features
Wide Input Range: 9V to 28V Current Mode Control 0.
