ISL6520集成电路（IC）的PMIC-稳压器-DCDC开关式控制器规格书PDF中文资料

The ISL6520 makes simple work out of implementing a complete control and protection scheme for a DC/DC stepdown converter. Designed to drive N-Channel MOSFETs in a synchronous buck topology, the ISL6520 integrates the control, output adjustment, monitoring and protection functions into a single 8 Lead package.
