... Flexible LED Pre-Driver General Description DD331 is a 4-channel LED pre-driver. It could provide constant-current to drive LED with four N-type MOSFETs and external resistors. The four output enable terminals are designed to drive LED with PWM functions. The maximum voltage and current in LED string are determined by specification of N-type MOSFET ...
