ISL95833HRTZ-T全新原装,RENESAS/瑞萨:
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
Both VRs utilize Intersil's Robust Ripple Regulator R3 Technology™. The R3 modulator has numerous advantages
compared to traditional modulators, including faster transient response, variable switching frequency during load
transients, and improved light load efficiency due to its ability to automatically change switching frequency.
ISL95833HRTZ-T
The ISL95833 has several other key features. Both outputs support either DCR current sensing with a single NTC
thermistor for DCR temperature compensation, or more precise resistor current sensing if desired. Both outputs come
with remote voltage sense, programmable VBOOT voltage, IMAX, and switching frequency, adjustable overcurrent
protection and separate Power-Good signals.
