PRODUCTION DATA
Only the loop controller device needs a resistor divider at the MSEL1 pin to program USER_DATA_01 (COMPENSATION_CONFIG) and FREQUENCY_SWITCH. The MSEL1 pin of secondary channels are not used. In this design, a moderate switching frequency of 650kHz achieves both a small design size and a high-efficiency operation. Use the MSEL1 pin program table to select the frequency option. See Table 6-8 for resistor divider code selection. With 650kHz switching frequency, two resistors to AGND and BP1V5 can be used to program compensation settings 30. To program all 32 compensation settings possible through MSEL1, resistor divider code 9 sets the switching frequency to 650kHz.
