Product Summary
The UCC3808ADTR-2 is a low power current mode push-pull PWM. The UCC3808ADTR-2 is an enhanced version of the UCC3808 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 of the UCC3808ADTR-2 discharges any filter capacitance on the CS pin during each cycle and helps minimize filter capacitor values and current sense delay.
