Push-Pull Regulator Positive Output Step-Up/Step-Down DC-DC Controller IC 8-SOIC
UCC2808AQDR-2Q1 일반적인 설명
The UCC2808A-xQ1 is a family of BiCMOS push-pull, high-speed, low-power, pulse-width modulators. The UCC2808A-xQ1 contains all of the control and drive circuitry required for off-line or DC-to-DC fixed frequency current-mode switching power supplies with minimal external parts count.
The UCC2808A-xQ1 dual output drive stages are arranged in a push-pull configuration. Both outputs switch at half the oscillator frequency using a toggle flip-flop. The dead time between the two outputs is typically 60 ns to 200 ns depending on the values of the timing capacitor and resistors, thus limiting each output stage duty cycle to less than 50%.
The UCC2808A-xQ1 family offers a variety of package options and choice of undervoltage lockout levels. The family has UVLO thresholds and hysteresis options for off-line and battery powered systems. Thresholds are shown in the ordering information table.
The UCC2808A-xQ1 is an enhanced version of the UCC2808 family. The significant difference is that the A versions feature an internal discharge transistor from the CS pin to ground, which is activated each clock cycle during the oscillator dead time. The feature discharges any filter capacitance on the CS pin during each cycle and helps minimize filter capacitor values and current sense delay.
