VP3882 Overview
Features The VP3882 is a versatile controller designed for use in Boost and SEPIC power regulator and topologies that needs an external low-side NMOSFET acting as primary switch. Besides cycleby-cycle current limiting, current mode control scheme also makes it wide bandwidth and good transient response. The current limit can be programmed simply with an external resistor.
