PMP9227 Reference Design

Texas Instruments

High Input Voltage Synchronous Buck Provides Two Independent Outputs of 28V at 2A and 16V at 4A

Description

The LM5119 controller allows the user to have two separate regulated outputs or the capability to combine the outputs (of the same voltage) into a two-phase regulator. This design operates from a 36V - 51V input and regulates 28V@2A (with transients up to 7A) and 16V@4A (with transients up to 6A).

Features
  • Allows for dual or single regulated outputs 36V - 51V input Greater than 96% efficiency Sequenced output voltage Board length is approximately 69 mm Test report is available
