The LD5805 is a 4-channel linear current controller which combines with a boost switching controller.It’s an ideal solution for driving high power LED backlights. The LD5805 can achieve high accuracy of constant current to 4 LED strings with 4 internal MOSFET. For each LED string, the current is adj ·Input Voltage range: 6V to 36V\n·Drives up to 4 strings in parallel, up to 250mA per string\n·LED current balance rate is ± 2.7%\n·Programmable switching frequency\n·PWM Input for PDIM or ADIM dimming controlUse PDIM mode: PWM Input frequency Range 100Hz ~ 1kHzUse ADIM mode: PWM Input fr;
