Hi:
Some questions about the 7.2 Typical Application in the TPSM8D6C24 datasheet are as follows:
Q1: Do AGND and PGND need an external connection?
Q2: If the output voltage is set to 3.3V, the VSEL Resistor Divider Code should be 9 according to Table 6-12, and the VSEL Resistor to AGND Code calculated according to Table 6-13 and formula 8 is 7.5. So should Code choose 7 or 8?
Q3: Section 7.2.2.7 states that "In this single-phase design, resistor divider code 3 is selected for 5-ms soft start and resistor to AGND code 0 is selected for the highest current limit thresholds and standalone configuration. "According to this statement, MSEL2 pin should select 9.09kΩ resistance and pull it up to BP1V5, 4.64kΩ resistance and pull it down to AGND. But why do MSEL2_A and MSEL2_B choose 0Ω resistance to ground in P147 reference circuit?
Q4: Can ADRSEL_A and ADRSEL_B be set to the same for dual-channel output?
Q5: What is the difference between NONE and Float in Table 6-17? Do both of these mean no resister to BP1V5?
Thanks,
Jochen
