The LM5007 Switching Regulator Functions Step-by-Step All Functions Required to Implement a Low-Cost, High-Efficiency, Buck Bias Regulator. This high voltage regulator contains an 80 volt, 0.7A N channel buck switch. The device is easy to apply and is available in MSOP-8 and thermally enhanced LLP-8 packages. The regulator is inversely proportional to V based on hysteresis control_INof the plan. This feature allows the operating frequency to maintain a relatively constant load and input voltage variation. Hysteresis control eliminates the need for control loop compensation while providing very fast load transient response. The smart current limit at the LM5007 forced off time is inversely proportional to V_OUT。 This current limit reduces load current foldback. Other protection features include thermal shutdown, VCC undervoltage lockout, gate drive undervoltage lockout, and maximum duty cycle limiting.
