LM5007EVAL: 10V @ 400mA, 12 ~ 75 Vin

Summary

The LM5007 Step down switching regulator features all of the functions needed to implement low cost, efficient, Buck bias regulators.

This high voltage regulator contains an 80V, 0.7A N-channel Buck switch. The regulator is based on hysteretic control scheme using an on-time inversely proportional to input voltage (VIN). This feature allows the operating frequency to remain relatively constant with load and input voltage voltage variations. The hysteretic control requires no control loop compensation, while providing fast load transient response.
