您好
我有一個使用 TLV61070A 的設計需求。
需求條件如下:
- 輸入電壓:1.0VDC至2.0VDC
- 輸出電壓:3.3VDC
- 輸出電流:500mA
我使用PSpice for TI進行模擬,輸入電壓:1VDC時,模擬結果輸出電壓:6.5988u,如下圖。
輸入電壓:2VDC時,模擬結果輸出電壓:3.2996,如下圖。
請問輸入電壓:1.0VDC 時,為何輸出電壓不是3.3VDC?

Hi,
thank you for using E2E.
our engineer is out of office.
He will reply tomorrow.
kind regards,
Johannes
Hi Tom,
TLV61070A supports 1.3v min voltage for start up. After the IC has already started up, the Vin can be supported down to 0.5V. But for start up phase, Vin has to be over 1.3V.
Best Regards,
Travis
