LM5007SD Products

The LM5007SD 0.5-A step-down switching converter features all of the functions needed toimplement a low-cost and efficient buck regulator. This high-voltage converter has an integrated80-V, 0.7-A N-channel buck switch and operates over an input voltage range of 9 V to 75 V. Thedevice is easy to implement and is provided in 8-pin VSSOP and thermally enhanced 8-pin WSONpackages.

The converter uses a hysteretic control scheme with a PWM on-time inversely proportionalto VIN. This feature allows the operating frequency to remain relativelyconstant with load and input voltage variations. The hysteretic control requires no loopcompensation and provides fast transient response. An intelligent current limit is implemented withforced off-time that is inversely proportional to VOUT. This currentlimiting scheme ensures short-circuit protection while providing reduced load current foldback.Other protection features include thermal shutdown with automatic recovery,VCC and gate drive undervoltage lockout, and maximum duty cyclelimiter.
