TEXAS INSTRUMENTS LM3430SD/NOPB 发光二极管驱动器, 1输出, 升压逐步上升, 6V-40V输入, 2MHz开关, 1A输出, WSON-12
The is a high voltage low-side N-channel MOSFET Controller ideal for use in a boost regulator, the LM3430 can power the LED backlight in LCD panels, such as in notebook PCs. It contains all of the features needed to implement single ended primary topologies. Output voltage regulation is based on current-mode control, which eases the design of loop compensation while providing inherent input voltage feed-forward. It includes a start-up regulator that operates over a wide input range of 6 to 40V. The PWM controller is designed for high speed capability including an oscillator frequency range up to 2MHz and total propagation delays less than 100ns. Additional features include an error amplifier, precision reference, line under-voltage lockout, cycle-by-cycle current limit, slope compensation, soft-start, external synchronization capability and thermal shutdown.
