No. Within 600us (typ) after startup, MAX17220 will detect the resistance on SEL pin (RSEL) to set the output voltage. It will not monitor the value of RSEL again until another power cycle. The purpose…
The maximum output voltage of the MAX17220 is 5V. The output voltage is determined by the resistance between SEL pin and ground. The table showing the relationship between output voltage and resistor selection…
You will not damage the MAX17220 if voltage is applied at the output and the input is left floating. The MAX17220 has a True Shutdown Mode, which completely disconnects the output from the input and ensures…
You can use resistors with values outside what is presented in the table. The table presents the values required for the specified voltages. For example if Rsel is 50kOhm Vout will fall between 3.5V and…
The maximum recommended inductor size to use with the MAX17220 is 4.7uH. The concern with using an inductor bigger than 4.7uH is that the output voltage ripple will be very small, so the part is likely…
