The LM3429-Q1 is a versatile high voltage N-channel MOSFET controller for LED drivers. It can be easily configured in buck, boost, buck-boost, and SEPIC topologies. It uses Predictive Off-time (PRO) control, a combination of peak current-mode control and a predictive off-timer, which eases loop compensation while providing inherent input voltage feed-forward compensation. The device includes a high-voltage startup regulator operating from 4.5V to 75V.
