Description

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%.
FEATURES
• Push-Pull Oscillator With Programmable Deadtime
• High-Current Totem-Pole Dual Output Stage Drives Push-Pull Configuration with 1-A Sink and 0.5-A Source Capability
• Can be Used in Push-Pull, Half-Bridge, or Full-Bridge Topologies
• Oscillator Synchronization Output
• 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
APPLICATIONS
• High Efficiency Cascaded Converters
• Inverters
• Electronic Ballasts
• Uninterruptable Power Supplies (UPS)
• AC or DC Links
