The LM5009MMX/NOPB step-down switching regulator has all the functions required to achieve a low-cost and efficient step-down regulator. The device can drive 150mA load current with 9.5V to 95V input source. The switching frequency can exceed 600kHz, depending on the input and output voltages. The output voltage can be set from 2.5V to 85V. The high voltage regulator consists of an N-channel step-down switch and an internal starting regulator. The device is easy to implement and packaged with 8-pin VSSOP and 8-pin WSON with enhanced heat dissipation. The regulator is based on the control scheme, and the conduction time is inversely proportional to the VIN. With this feature, the operating frequency of the device can be kept relatively constant when the load and input voltage change. The control scheme does not need any loop compensation and can achieve ultra fast transient response. The device realizes intelligent current limiting, and its forced closing time is inversely proportional to VOUT. This scheme can ensure short circuit control while providing less turnback. Other features include thermal shutdown, VCC undervoltage lockout, gate driven undervoltage lockout, and maximum duty cycle limiter.
