VP3482 Description
Features The VP3482 is a versatile controller designed for use in Boost, SEPIC and Flyback power converter 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.
