ISL6316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 ISL6316 controls microprocessor core voltage regulation by driving up to 4 synchronous-rectified buck channels in parallel. Multiphase buck converter architecture uses interleaved timing to multiply channel ripple frequency and reduce input and output ripple currents. Lower ripple results in fewer components, lower component cost, reduced power dissipation, and smaller implementation area.

Microprocessor loads can generate load transients with extremely fast edge rates. The ISL6316 features a high bandwidth control loop and ripple frequencies up to >4MHz to provide optimal response to the transients.
