LD7400

LD7400 2012/3/7 Boost Controller for LED Backlighting REV: 00 General Description The LD7400 is an asynchronous current mode boost controller, can operate over a wide input range from 10.5V to 28V. The current mode architecture improve It’s ideal to program the brightness of LED Backlight or LED lighting and can efficiently manage Power MOSFET thermal transient response and simplify the loop compensation. The Device features internal slope compensation, input voltage under-voltage lockout, output voltage short circuit protection, cycle-by-cycle current limit, programmable oscillator frequency, and thermal shutdown protection. The LD7400 is available in an SOP-8 package.
