TPS5430: DCDC输出负电压

Part Number: TPS5430
Other Parts Discussed in Thread: TPS54160, TPS54360

TPS5430可以将+24V的输入电压转换成-15V的输出电压并长期稳定运行吗

  • HI

        不行,按照你的条件你需要选择输入电压大于24+15即39V以上的降压芯片,你可以选择TPS54160系列或者其它输入电压大于39V以上的降压芯片.

        参考设计文档: https://www.ti.com.cn/cn/lit/an/slva317b/slva317b.pdf,  按照电流需求选择TPS54160系列中的版本,例如3.5A的TPS54360之类。
