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%.

The UCC28089 is optimized for use as the primary-side companion controller for a cascaded converter that has secondary-side control. The device incorporates dead-time programming. The synchronization output also provides dead-time information. The retry and soft-start duration scales with the oscillator clock frequency for high performance fault recovery.

The UCC28089 also provides primary side under-voltage protection (UVLO), and over-current protection.
