What are the key features of UCC28089DG4?
- Primary-side PWM control up to 1 MHz switching frequency enabling compact transformer and passive component design in isolated power supplies
- Wide 8.5 V to 14 V input voltage range with 1 A peak gate drive output current supporting efficient MOSFET switching in flyback and forward topologies
- Single-function 8-pin SOIC package (R-PDSO-G8) minimizing board space while simplifying isolated DC-DC converter design with minimal external components
What is UCC28089DG4 used for?
The UCC28089DG4 is designed for primary-side control in isolated flyback and forward DC-DC converters used in power adapters, industrial power supplies, and telecommunications equipment. Its 1 MHz switching capability allows designers to use smaller magnetic components and output capacitors, reducing overall power supply size and cost. It is also applied in auxiliary power supply stages within motor drives, solar inverters, and UPS systems requiring compact isolated regulation.

Frequently Asked Questions
Which offline converter designs can use UCC28089DG4 as the primary-side PWM controller?
UCC28089DG4 is intended for PWM-controlled flyback and forward converter designs, with operation up to 1 MHz and a gate-drive output rated up to 1 A.
How much bias supply range should the controller rail provide?
The controller is specified around an 8.5 V to 14 V input range, so power-supply designers should keep the bias rail inside that window during startup and steady-state operation.
For layout and sourcing, what package detail should be checked against the BOM?
This orderable uses an 8-pin SOIC style package, so buyers and layout engineers should confirm the footprint, lead finish, and approved alternate package before substitution.
