D
Oscillator Synchronization Output  
The UCC28089 is a versatile BiCMOS controller for  
dc-to-dc or off-line fixed-frequency switching power  
supplies. The UCC28089 has dual alternating output  
stages in dual-alternating push-pull configuration. Both  
outputs switch at half the oscillator frequency using a  
toggle flip-flop and duty cycle is limited to less than 50%.  
Low Start-Up Current of 130 µA and 1.4-mA
