您好!
通过查看电荷泵选择表、我找不到支持+5V ->-40V 转换的器件?
满足此要求的器件是否确实存在于 TI 的"现成"中?
此致、
帕维尔

你好 Pavel
LM5088不是电荷泵器件、但可用作反向降压/升压。 请参阅 https://www.ti.com/lit/an/snva856a/snva856a.pdf

你好 Pavel
如果负载电流仅为几 mA、我认为 LM5088太大...
我不太了解电荷泵器件。 请在 https://www.ti.com/power-management/non-isolated-dc-dc-switching-regulators/charge-pump-inductorless/products.html 上查看您是否能找到合适的器件 。
