Texas Instruments LM22671
The LM22671 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 500 mA of load current. The LM22671 device also has built-in thermal shutdown and current limiting to protect against accidental overloads.| Part No. | LM22671 |
