TPS61023: 关于TPS61023的电感选型问题

Part Number: TPS61023

工程师你好,

我们计划使用TPS61023,使4.5-4.7v输入变为5v 2a输出。

1.在TPS61023的规格书中,通过公式5,计算得知电感电流最小应选择2.8a的,是否证明可以选择温升电流等于3a的电感?

2.另外,规格书中,提到“The TPS61023 is designed to work with inductor values between 0.37 μH and 2.9 μH”,请问该感值是如何计算的?

3.若使用大于2.9uH的电感,会有什么风险呢?

感谢。
