The LM22676MR-ADJ/NOPB is a SIMPLE SWITCHER? Step-down Switching Regulator with precision enable provides all of the functions necessary to implement an efficient high voltage step-down regulator using a minimum of external components. This easy to use regulator incorporates a 42V N-channel MOSFET switch capable of providing up to 3A of load current. 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. This regulator is available in an adjustable output voltage version and good transient response. A precision enable input allows simplification of regulator control and system power sequencing. In shutdown mode the regulator draws only 25μA and Built in soft-start 500μs saves external components. The LM22676 also has built in thermal shutdown and current limiting to protect against accidental overloads.
