Description	High Efficiency High-Side N-Channel Controller for Switching Regulator
Datasheet	LM3-477.pdf
Note	This datasheet PDF includes multiple part numbers: LM3477A, LM3. Please refer to the document for exact specifications by model.

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

include internal soft-start and output over voltage protection. The internal soft-start reduces inrush current. Over voltage protection is a safety feature to ensure that the output voltage stays within regulation. The LM3477A is similar to the LM3477. The primary difference between the two is the point at which the device transitions into hysteretic mode. The hysteretic threshold of the LM3477A is one-third of the LM3477. n Frequency compensation optimized with a single capacitor and resistor n.
