What are the key features of UCC3813PW-0G4?
- Current-mode PWM control with up to 1 MHz switching frequency enables high-frequency compact converter designs with reduced magnetics size
- 1 A peak gate drive output allows direct drive of power MOSFETs in low-to-medium power flyback, forward, and boost topologies
- 7.5 V to 12 V supply range is compatible with common bias voltages from auxiliary windings and dedicated supply rails
- Precision 5 V internal reference and accurate oscillator ensure tight duty cycle control and predictable converter performance
- 8-pin TSSOP ultra-compact package minimizes PCB footprint for space-constrained power supply designs
What is UCC3813PW-0G4 used for?
The UCC3813PW-0G4 is widely used as the PWM controller in offline flyback and forward converters for low-to-medium power AC/DC adapters, set-top box power supplies, and telecom equipment. It is also deployed in DC/DC converters in industrial and instrumentation power supplies where current-mode control with high switching frequency is required for fast transient response and tight output regulation. The device's compact TSSOP package makes it well-suited for high-density power module designs.

Frequently Asked Questions
Which converter controllers can use UCC3813PW-0G4?
This current-mode PWM controller operates from 7.5 V to 12 V and supports switching up to 1 MHz for compact power-conversion designs.
How should engineers size the external gate-drive stage?
The device can deliver up to 1 A gate drive, so MOSFET gate charge, switching frequency, losses, and thermal margin require validation.
For BOM qualification, what electrical and package details must remain fixed?
Preserve the 8-pin TSSOP, 7.5 V to 12 V supply range, 1 MHz capability, current-mode control, compliance, and traceability.
