Intersil ISL6363CRTZ

控制器，Intel VR125V ~ 12V0.25V ~ 1.52V

Overview

Fully compliant with VR12™ specifications, the ISL6363CRTZ provides a complete solution for microprocessor core and graphics power supplies. It provides two Voltage Regulators (VRs) with three integrated gate drivers. The first output (VR1) can be configured as a 4, 3, 2 or 1-phase VR while the second output (VR2) is a 1-phase VR. The two VRs share a serial control bus to communicate with the CPU and achieve lower cost and smaller board area compared with a two-chip approach. Based on Intersils Robust Ripple Regulator R3 Technology™, the PWM modulator, compared to traditional modulators, has faster transient settling time, variable switching frequency during load transients and has improved light load efficiency with its ability to automatically change switching frequency. The ISL6363CRTZ has several other key features. Both outputs support DCR current sensing with a single NTC thermistor for DCR temperature compensation or accurate resistor current sensing. Both outputs come with remote voltage sensing, programmable VBOOT voltage, serial bus address, IMAX, TMAX, adjustable switching frequency, OC protection and separate power-good indicators. To reduce output capacitors, the ISL6363CRTZ also has an additional compensation function for PS1/2 mode and high frequency load transient compensation.
