General Description

The LM3477/A is a high-side N-channel MOSFET switching regulator controller.

It can be used in topologies requiring a high side MOSFET such as buck, inverting (buck-boost) and zeta regulators.

The LM3477/A's internal push pull driver allows compatibility with a wide range of MOSFETs.
