The RT8880BGQW from Richtek is a 3+2 phase PWM controller compliant with the AMD SVI2 Voltage Regulator Specification. It supports both CPU core (VDD) and Northbridge (VDDNB) power domains, making it suitable for AMD SVI2 mobile CPU applications and laptop computers.
This controller features Richtek's proprietary G-NAVP topology, enabling easy setting for AMD AVP requirements. It offers dynamic load-line and zero load-line support, along with diode emulation mode at light load conditions for improved efficiency. The RT8880B includes an SVI2 interface for AMD power management protocols and an integrated ADC for reporting voltage and current values.
Key electrical specifications include a supply voltage range of 4.5V to 5.5V and a switching frequency of 300kHz. It provides 2 outputs and 3 output phases. The device also incorporates immediate over-voltage, under-voltage, and negative-voltage protections, along with UVLO and a programmable dual OCP mechanism. The DAC accuracy is 0.5%.
Packaged in a 52-lead WQFN (6x6mm) with surface mount mounting type, the RT8880BGQW operates within an ambient temperature range of -40°C to 85°C. It is RoHS3 compliant and Halogen Free.
