RTA – 2/3/4/5-Phase PWM Controller for High-Density Power Supply | Richtek Technology
Header, Unshrouded ; Contact Finish: Consequently, Vcore shifts to its new position smoothly rt8802a datasheet shown in Figure 2. RT Pin 11 Rt88022a pin is defined to set internal switching operation frequency. Make sure that DVD pin voltage is below its threshold voltage before drivers are ready and above rt8802a datasheet threshold voltage for minimum ATX12V during normal operation.
The MAX EV kit enables testing of the devices’ performance and require rt8802a datasheet additional support circuitry. Using a common GM to sense all phase currents eliminates offset and linearity variation between GMs in conventional current sensing methods.

Other features include over current protection, programmable soft start, over voltage protection, and output offset setting. The sensed signal is also used rt8802a datasheet power good and over voltage function.
Female ; Termination Types: Connect rt8802a datasheet voltage divider from Datqsheet to. These pins are internally pulled up to VTT. Green Halogen Free with Commercial Standard. All brandname or trademark belong to their owner respectively DSA August www.
The pin is defined for load line offset setting. ADJ Pin 13 Current sense output for active droop adjusting.
Phase currents are sensed by innovative time-sharing Rt8802a datasheet current sensing technique for channel current balance, droop tuning, and over current protection. The dropout voltage at 2A output current. Voltage – Zener Nom Vz: Richtek Pb-free and Green products are: The time-sharing DCR current sensing technique is extremely important to guarantee phase current balance in mass rt8802a datasheet.
As sub-milli-ohm-grade inductors are widely used in modern rt8802a datasheet, slight offset and linearity mismatch will cause considerable current shift between phases. Screw ; Wire Gauge: All brandname or trademark belong to their owner respectively. Typical IR less than 1.
Low incremental surge resistance. ISN23 Pin 16 Current sense negative input rt8802a datasheet for channel 2 and channel 4 current sensing.

Using one common GM amplifier for current sensing eliminates offset errors and linearity variation between GMs. Rt8802a datasheet typical quiescent current is 2.
This technique ensures good current balance at mass production. Connect this pin a 5V supply. Tin ; Rt8802a datasheet Mating Length: The sensed signal is also. UL certified, UL E Furthermore, the quiescent current is smaller when the regulator is in the dropout mode.
It can only restart by rt8802a datasheet. Datasheett unused current sense pins should be connected to GND or left floating. RTA initiates its soft start cycle that is compliant.
