Key Features
- 1A peak gate drive output enables fast MOSFET switching in high-frequency DC-DC converter designs
- Current-mode PWM control provides inherent cycle-by-cycle current limiting and superior line transient response
- 8.2V to 12V operating range (nominal 10V) matches standard bias supply voltages in telecom and industrial power stages
- Compact 8-pin TSSOP (R-PDSO-G8) package minimizes PCB footprint for space-constrained power designs
Applications
The UCC2813PW-1G4 is used as the primary PWM controller in isolated and non-isolated DC-DC converter power stages for telecom equipment, industrial power supplies, and server power modules. Its current-mode control architecture makes it well-suited for flyback, forward, and boost topologies where precise current regulation and fast loop response are required. The 8-pin TSSOP format supports high-density power modules and compact adapter designs where board area is limited.

Frequently Asked Questions
What is the input voltage range and gate drive capability of the UCC2813PW-1G4?
The UCC2813PW-1G4 operates from a supply voltage of 8.2V minimum to 12V maximum, with a nominal design point of 10V. Its gate drive output delivers up to 1A peak current, enabling fast turn-on and turn-off of power MOSFETs in high-frequency switching converters.
What control mode does the UCC2813PW-1G4 implement?
The UCC2813PW-1G4 implements current-mode pulse width modulation (PWM) control. This technique samples the inductor or primary switch current each cycle, providing inherent cycle-by-cycle peak current limiting, excellent audio susceptibility, and simplified compensation compared to voltage-mode control.
What package does the UCC2813PW-1G4 use and is it lead-free?
It is housed in an 8-pin TSSOP (Thin Shrink Small Outline Package), JESD-30 code R-PDSO-G8. The JESD-609 code e4 confirms full RoHS lead-free compliance, making it suitable for eco-regulated markets in Europe, Asia, and North America.
In which converter topologies can the UCC2813PW-1G4 be used?
The UCC2813PW-1G4 is compatible with flyback, forward, boost, and buck-boost power converter topologies. Its current-mode architecture and 1A drive strength make it particularly effective in isolated offline supplies, battery chargers, and point-of-load DC-DC converters in the 8.2V to 12V bias range.
