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.
The LM22673 device is a member of Texas Instruments SIMPLE SWITCHER® family. The SIMPLE SWITCHER® concept provides for an easy to use complete design using a minimum number of external components and the TI WEBENCH® design tool. TIs WEBENCH® tool includes features such as external component calculation, electrical simulation, thermal simulation, and Build-It boards for easy design-in.
