Texas Instruments LM5141QRGEVM评估模块 (EVM)
Texas Instruments LM5141QRGEVM降压转换器评估模块 (EVM) 利用峰值电流模式控制提供功能齐全的降压电源。该模块可助于设计人员评估LM5141-Q1同步降压控制器的运行和性能。该评估板在电流为5A时提供5.0V电压。标称输入电压范围为8V-18V。该器件可配置并可设置为在440kHz或2.2MHz时切换。
特性
- VIN 5.5V至42V
- 5V （5A时）
- 2.2MHz运行，以避免汽车AM频段
- 低关断电流IQ： 10µA
- 低待机电流：35μA（无负载情况下的稳定输出）
必要设备
- Power supply
- The power supply should be capable of 50V/10A
- Electronic loads
- The electronic load should be capable of 10V/10A used in constant current mode
- Oscilloscope
- An oscilloscope and 10x probes with at least 20MHz bandwidth are required
- Meters
- A current meter is required to measure the input current accurately
- The maximum current rating of the meter should be carefully considered
- The input current can be as high as 4.5A with the output at full load at the minimum input voltage
- The output voltage should be monitored with a voltage meter capable of monitoring up to 10V
