Περιγραφή

The ISL6267 is designed to be completely compliant with AMD Fusion™ specifications. The ISL6267 controls two Voltage Regulators (VRs), with three integrated gate drivers. The first VR can be configured as 3-, 2-, or 1-phase VR, while the second output can be configured as 2- or 1-phase VR, providing maximum flexibility. The two VRs share the serial control bus to communicate with the CPU and achieve lower cost and smaller board area compared with two-chip solutions. The PWM modulator of the ISL6267 is based on Intersil’s R3 (Robust Ripple Regulator) Technology™. Compared with the traditional multi-phase buck regulator, the R3 modulator commands variable switching frequency during load transients, achieving faster transient response. With the same modulator, it naturally goes into pulse frequency modulation in light load conditions, which achieves higher light load efficiency and extends battery life. The ISL6267 has several other key features. Both outputs support DCR current sensing with a single NTC thermostat for DCR temperature compensation or accurate resistor current sensing. Both of the outputs utilize remote voltage sense, adjustable switching frequency, current monitor, OC protection, independent power-good indicators, temperature monitors, and a common thermal alert.
