DESCRIPTION

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

Typical Run Current

Over-Current Shutdown

Digitally Controlled Over-Current/Retry

Feature

Undervoltage Lockout With Hysteresis

TYPICAL APPLICATION
