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.
Features
- 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.
