Planning to use it to step 5V down to 3.3 through both LDOs. Can someone provide an efficiency for this part? Hoping to do some some power estimates.</P><P>Best regards.</P> Wed, 02 Jul 2025 21:36:40 GMT https://community.nxp.com/t5/Power-Management/FS26-DC-DC-Efficiency/m-p/2127591#M4470 greenwichmeanie 2025-07-02T21:36:40Z https://community.nxp.com/t5/Power-Management/FS26-DC-DC-Efficiency/m-p/2127698#M4472 <P>Hi&nbsp;</P> <P>You can download the power dissipation tool for getting LDO related information.</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="guoweisun_0-1751511828506.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/345884i0852147402D44E0A/image-size/medium?v=v2&amp;px=400" role="button" title="guoweisun_0-1751511828506.png" alt="guoweisun_0-1751511828506.png" /></span></P> <P>&nbsp;</P> <P><A href="https://www.nxp.com/products/FS26#documentation" target="_blank">FS26 | Safety System Basis Chip with Low Power, for ASIL D Systems | NXP Semiconductors</A></P> Thu, 03 Jul 2025 03:04:12 GMT https://community.nxp.com/t5/Power-Management/FS26-DC-DC-Efficiency/m-p/2127698#M4472 guoweisun 2025-07-03T03:04:12Z
