LM5008EVAL: 10V @ 300mA, 12 ~ 95V in

The LM5008 Step down switching regulator features all of the functions needed to implement low cost, efficient, Buck bias regulators. This high voltage regulator contains a 100V, 0.5A 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. Additional protection features include: Thermal Shutdown, VCC undervoltage lockout and maximum duty–cycle limiter.

LM5008 can be used in numerous applications to efficiently regulate step down higher voltage inputs. This regulator is well suited for 48V telecom and the new 42V automotive power bus ranges.
