描述
The current mode switching regulator is designed fordriving a 6V rated N-channel MOSFET and features programmable slope compensation, soft-start, and constant frequency operation, minimizing noise even with lightloads. The LTC4267 includes an onboard error ampli?er and voltage reference allowing use in both isolated and non-isolated con?gurations.? The LTC4267 is available in space saving, low pro? le16-pin SSOP or DFN packages.
