2 / 9 page 2 AN1574.2 November 29, 2010 Disabling/enabling Function The ISL85033 evaluation board contains S1, S2 switches to enable or disable each of the channels, thus allowing low quiescent current state. Table 1 details this function. If EN1 or EN2 are floating, then the outputs will start in the sequencing described in the data sheet section on output sequencing and also summarized in Table 2. SYNC Control The ISL85033 evaluation board has an SI pin that allows external synchronization frequency to be applied. Default board configuration has R18 = 0 to GND, which defaults to the internal selected switching frequency. Removing R18 allows the synchronization to be external between 600kHz to 4MHz. Do not leave this pin floating. TABLE 1. SWITCH SETTINGS S1 S2 ON/OFF CONTROL ON OFF Enable VOUT1; Disable VOUT2 OFF ON Disable VOUT1; Enable VOUT2 ON ON Enable VOUT1; Enable VOUT2 OFF OFF Disable VOUT1; Disable VOUT2 TABLE 2. EN1 EN2 VOUT1 VOUT2 NOTE High Floating First After VOUT1 > 90% Floating High After VOUT2 >90% First High High Same time as VOUT2 Same time as VOUT1 Floating Floating Not Allowed Application Note 1574 |
