多输出转换开关降压电路和两个积极的线性稳压器组成。虽然该集成电路的基本应用电路提供了一个低成本的多输出电源,需要目前有限的线性稳压器输出(开关降压已是当前有限)的设计,需要咨询本应用笔记。如果短裤线性稳压器的输出,或失误可能会导致功耗的外部旁路元件将超过预期,应采用限流。与折返电流限制电路,就可以了进一步的保护。本应用笔记详细的设计和实施当前限制MAX1864积极的线性稳压器的。Maxim > App Notes > AUTOMOTIVE

APPLICATION NOTE 3654
Current Limiting for the MAX1864 Auxiliary Regulator
Abstract: The MAX1864 is a low-cost, multiple-output converter consisting of a switching buck circuit and two
positive linear regulators. Although this integrated circuit's basic application circuit offers a low cost multiple
output supply, designs that require current limited linear regulator outputs (the switching buck is already
current limited) need to consult this application note. If shorts are expected at the linear regulator outputs, or
where mishaps can cause the power dissipation of the external pass element to be exceeded, current limiting
should be employed……
