I'm trying to design a circuit using the that will output roughly 28V. I am using 1Mohm and 29.4kohm for the feedback resistors and should output 27.8V according to the equation on 9.2.2.1.
The input voltage is roughly 5.0V with about 200mA. When measuring the output voltage, I get anywhere between 14V to 17V. I've measured the Vref (FB voltage) at about 300mV, whereas the datasheet states that the typical Vref should be around 795mV.
Maybe there is an issue with my design seeing as the IC gets pretty hot.
