Analog Devices Switching Regulators: Why does the datasheet say that increasing the voltage on the Bias pin of the LTM8065 reduces efficiency?
The bias pin can be applied with a voltage from 3.2V to 19V. Since the LDO is connected inside the Bias pin, the loss of the LDO increases when the applied voltage is high. If you want to use it with high efficiency, please use the voltage applied to the Bias pin at a voltage close to 3.2V.
