SNVSCC1 May 2022 LM5143A-Q1
PRODUCTION DATA
The LM5143A-Q1 has two outputs that can operate independently. Both VOUT1 and VOUT2 can be set at 3.3 V or 5 V without installing external feedback resistors. Alternatively, set the output voltages between 0.6 V and 55 V using external feedback resistors based on Equation 5. See Table 9-1 and Figure 9-8. Connect MODE directly to AGND for independent outputs.
