(1) Output voltage cannot exceed input voltage. Refer to Input vs. Output graphs provided. (2) Full Feature module but without the SEQ (Sequencing) Pin 34 installed. This eliminates the need for external pull-up resistor when Sequencing feature is not being used. (3) If the Sequencing feature will not be used, the SEQ Pin 34 needs to be tied to a 1.8-3.3V source via a 10k resistor. See Full specification for details. Typical Application Circuit Recommendation 1. TRIM resistor Rup should be connected to the i6A module as close as possible. 2 i6A4W Series
