Custom register 5 provides output voltage margin high (VOMH) and output voltage margin low (VOML) settings. This register works in conjunction with PMBus OPERATION command to raise or lower the output voltage by a specified amount. This register settings described in Table 14 are also used together with the fine adjustment setting described in Table 12. For example, setting fine adjustment to +9% and margin to +12% changes the output by +22.08%, whereas setting fine adjustment to –9% and margin to –9% change the output by –17.19%
