SKA9270 Datasheet
SKA9270 Price The regulators are intended to regulate the computer system AGP (2X/4X) power, the 2.5V clock power, and the l.8V power for North/South Bridge core voltage and/or cache memory circuits. All controllers can drive NPN or NMOSFET pass transistor. A special scheme empoly driver voltage could be higher than VDD when driving NMOSFET through the 12V power. SKA9270 on stock
For the open loop gain of this operational amplitier, if the Pin 7 control current is ICONTROL and the Pin 11 external resistance is Ro, then: Av - gm Ro - ICONrROLX R 2 KqT To eliminate the distortion created by the differential input, the input bias diode and its bias circuit consist of the following: bias diodes Di and D2, current mirrors (1) and (2), and the Pin 5 bias pin current mirror that consists of the transistors Qi to Q6 and the resistance Rl. This circuit eliminates the distortion that occurs as a result of using the differential input open loop. In the buer circuit, Pin 12 is the buffer input and Pin 14 is the buffer output. In the bulfer circuit, the emitter follower consists of the active load of the NPN transistor, Q17, and its active load, Q16. The VF difference created by the emitter follower is eliminated by the emitter follower which consists of the PNP transistor Q18 and resistor Rs. Also, the gain is determined by the ratio of the signal source resistance RIN and the diode impedance. |
