LM5088 - Wide Input Range Non-Synchronous Buck Controller

General Description

The LM5088 high voltage non-synchronous buck controller

Key Features

  • all the necessary functions to implement an efficient high voltage buck converter using a minimum number of external components. The LM5088 can be configured to operate over an ultra-wide input voltage range of 4.5V to 75V. This easy to use controller includes a level shifted gate driver capable of controlling an external N-channel buck switch. The control method is based upon peak current mode control utilizing an emulated current ramp. The use of an emulated control ramp reduces noise sensitiv.
