Texas Instruments LM22678
The LM22678 switching regulator provides all of the functions necessary to implement an efficient highvoltage step-down (buck) regulator using a minimum of external components. This easy-to-use regulator incorporates a 42-V N-channel MOSFET switch that can provide up to 5 A of load current. The LM22678 device also has built-in thermal shutdown, and current limiting to protect against accidental overloads.| Part No. | LM22678 |
