More Information

The LM22673 switching regulator provides all of the functions necessary to implement an efficient high voltage step-down (buck) regulator using a minimum of external components. This easy to use regulator incorporates a 42 V N-channel MOSFET switch capable of providing up to 3 A of load current. Excellent line and load regulation along with high efficiency (> 90%) are featured. Voltage mode control offers short minimum on-time, allowing the widest ratio between input and output voltages. Internal loop compensation means that the user is free from the tedious task of calculating the loop compensation components. Fixed 5 V output and adjustable output voltage options are available. A switching frequency of 500 kHz allows for small external components and good transient response. An adjustable soft-start feature is provided through the selection of a single external capacitor. In addition, the switch current limit can be programmed with a single external resistor, allowing solution optimization. The LM22673 device also has built-in thermal shutdown, and current limiting to protect against accidental overloads.
