DESCRIPTION
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%.
