♠ TPS255xx Precision Adjustable Current-Limited Power-Distribution Switches
The LM5007 0.5-A step-down switching converter features all of the functions needed to implement a low-cost and efficient buck regulator. This highvoltage converter has an integrated 80-V, 0.7-A Nchannel buck switch and operates over an input voltage range of 9 V to 75 V. The device is easy to implement and is provided in 8-pin VSSOP and thermally enhanced 8-pin WSON packages.
The converter uses a hysteretic control scheme with a PWM on-time inversely proportional to VIN. This feature allows the operating frequency to remain relatively constant with load and input voltage variations. The hysteretic control requires no loop compensation and provides fast transient response. An intelligent current limit is implemented with forced off-time that is inversely proportional to VOUT. This current limiting 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 cycle limiter.
