The LM22673QMRE-ADJ switching regulator uses a minimum of external components to provide all the functions required to implement a high-efficiency high-voltage buck regulator. This easy-to-use regulator integrates a 42V N-channel MOSFET switch capable of delivering up to 3A of load current. And features excellent line and load regulation and high efficiency (> 90%). Voltage-mode control provides a short minimum on-time, enabling the widest ratio between input and output voltages. Internal loop compensation means that the user does not have to undertake the tedious work of calculating loop compensation components. This regulator is available in both fixed 5V output and adjustable output voltage options. The 500kHz switching frequency enables the use of small external components and good transient response. An adjustable soft-start characteristic is provided by selecting a single external capacitor. Additionally, the frequency is adjustable from 200kHz to 1MHz using a single external resistor. The LM22673 device also has built-in thermal shutdown and current limiting to protect the device from accidental overloading.
