What are the key features of UCC3800PWG4?
- Current-mode PWM control at frequencies up to 1000 kHz enabling high-frequency compact SMPS designs with fast transient response and cycle-by-cycle current limiting
- 1 A peak gate drive output sufficient to directly drive power MOSFETs in flyback, forward, and buck-boost converter topologies without external gate driver buffers
- Wide input voltage range of 7.5 V to 12 V in a compact 8-pin TSSOP package for easy integration into isolated and non-isolated switch-mode power supplies
What is UCC3800PWG4 used for?
The UCC3800PWG4 is used as the primary control IC in offline flyback converters, forward converters, and DC/DC power modules where current-mode control at up to 1000 kHz enables small magnetic component size and rapid load-transient response. It is also applied in industrial 24 V power supplies, telecom DC/DC converters, and battery charger stages where the 1 A gate drive capability simplifies MOSFET switching without auxiliary driver circuits.

Frequently Asked Questions
Which supply range should a power-supply designer allow for UCC3800PWG4?
UCC3800PWG4 is specified for a 7.5 V to 12 V input range with a 10 V nominal operating point, supporting current-mode PWM control in offline and DC/DC converters.
How much gate-drive capability is available for compact switch-mode converter designs?
The controller provides a 1 A gate-drive output and supports switching frequencies up to 1000 kHz, helping designers drive external MOSFET stages in regulated power supplies.
What assembly details should purchasing confirm before approving this order code?
Confirm the 8-pin TSSOP footprint, Pb-free status, and date-code availability, because UCC3800PWG4 is an obsolete orderable variant used in legacy power designs.
