PRODUCTION DATA.
Refer to the PDF data sheet for device specific package drawings
To minimize output voltage regulation error, the LM25180 senses the reflected secondary voltage when the secondary current reaches zero. The feedback (FB) resistor, which is connected between SW and FB as shown in Figure 19, is determined using Equation 8, where RSET is nominally 12.1 kΩ.
