ISL95831集成电路（IC）的特殊用途稳压器规格书PDF中文资料

The ISL95833 Pulse Width Modulation (PWM) controller IC provides a complete solution for IMVP-7/VR12 compliant microprocessor and graphic processor core power supplies. It provides the control and protection for two Voltage Regulators (VRs). The first VR, typically for VCORE, incorporates 1 integrated driver and can operate in 2- or 1-phase configurations. The second VR, typically for Graphics, is a single phase regulator incorporating an integrated driver. The two VRs share a serial control bus to communicate with the CPU and achieve lower cost and smaller board area compared with the two-chip approach.
