rt8857应用电路及参数
4/3/2/1-phase pwm controller with embedded drivers for cpu core power supply
the rt8857/a is a 4/3/2/1-phase synchronous buck controller with 2 integrated mosfet drivers for intel vr11.1/vr10.x and amd k8/k8_m2 cpus power application. rt8857/a uses differential inductor dcr current sense to achieve phase current balance and active voltage positioning. other features include adjustable operating frequency, adjustable soft start, power good indication, external error-amp compensation, over voltage protection, over current protection, vrhot sensing and imon for various applications. rt8857/a comes to a small footprint with wqfn-48l 7x7 package
features
• 12v power supply voltage
• 4/3/2/1-phase power conversion
• 2 embedded mosfet drivers
• internal regulated 5v output
• vid table for intel vr11.1/vr10.x and amd k8/k8_m2 cpus
• continuous differential inductor dcr current sense
• adjustable soft start
• adjustable frequency
• power good indication
• adjustable over current protection
• over voltage protection
• vrhot sensing with external thermistor
• imon output current indication
• power state indicator (psi)
• support mosfet power stage input voltage (vin) down to 5v (rt8857a only)
• small 48-lead wqfn package
• rohs compliant and halogen free
application
• desktop cpu core power
• low voltage, high current dc/ dc converter
