What are the key features of UCC3804PWG4?
- Current-mode PWM control with cycle-by-cycle current limiting for precise, fast-response power regulation
- 1A peak gate drive output current enabling efficient driving of large power MOSFETs in compact SMPS designs
- 8-pin TSSOP (JESD-30 R-PDSO-G8) surface-mount package with 9V–12V input range for flexible topology support
What is UCC3804PWG4 used for?
The UCC3804PWG4 is used in switch-mode power supplies including flyback, forward, and boost converter topologies where current-mode control is preferred for tight regulation and inherent overcurrent protection. It suits telecom power modules, industrial DC-DC converters, and off-line power supplies requiring reliable, high-frequency switching. The 1A gate drive capability allows direct MOSFET switching without an external gate driver in many applications.

Frequently Asked Questions
What control method does the UCC3804PWG4 use?
The UCC3804PWG4 uses current-mode PWM (pulse-width modulation) control. This technique senses the inductor or switch current each switching cycle, enabling cycle-by-cycle current limiting, improved line rejection, and faster load transient response compared to voltage-mode control.
What is the input voltage range for the UCC3804PWG4?
The UCC3804PWG4 operates from a supply voltage of 9V minimum to 12V maximum, with a nominal operating voltage of 10V. This range is typical for use alongside an auxiliary winding supply in off-line power supply designs or from regulated 12V bus in DC-DC converters.
What package does the UCC3804PWG4 come in?
The UCC3804PWG4 is housed in an 8-pin TSSOP surface-mount package (JESD-30 code R-PDSO-G8). The compact TSSOP footprint is suitable for high-density power supply PCB layouts where space is at a premium.
Is the UCC3804PWG4 RoHS compliant?
Yes, the UCC3804PWG4 is RoHS compliant as indicated by the Pb-free code (JESD-609 code e4) and the G4 suffix in the part number, which denotes lead-free, green packaging meeting current environmental regulations for global distribution.
