【文字介绍】 The LM5140EVM evaluation module helps designers evaluate the operation and performance of theLM5140-Q1 Synchronous Buck Controller. The EVM operates over the input voltage range of 3.8 V to 42 V. The EVM provides two independent outputs, a 3.3-V output with a maximum load current of 6 A, and a 5-V output with a maximum load current of 5 A. The device offers configurability and can be set up to switch at 440 kHz or 2.2 MHz |
