Key Features

  • Current-mode PWM control technique providing inherent cycle-by-cycle overcurrent limiting and improved transient response in switched-mode power supply designs
  • High switching frequency capability up to 1000 kHz enabling the use of smaller magnetic components and capacitors for compact power converter designs
  • Wide input voltage range of 7.5V to 12V (nominal 10V) with strong 1A gate drive output for driving power MOSFETs in boost, flyback, and forward converter topologies
  • Compact 8-pin SOIC package (JESD-30 Code R-PDSO-G8) with RoHS-compliant construction suitable for high-density power management PCBs

Applications

The UCC3807D-1G4 is designed for use in offline flyback converters, boost regulators, and isolated DC-DC power supplies where current-mode control is required for fast response and robust overcurrent protection. It is commonly applied in power adapters, telecom power modules, industrial power supplies, and battery chargers operating in the 7.5V to 12V input range. Its high-frequency capability allows engineers to design ultra-compact power stages for embedded and portable systems.

Frequently Asked Questions

What control mode does the UCC3807D-1G4 use?

The UCC3807D-1G4 uses current-mode pulse width modulation (PWM) control, which senses the inductor or transformer current each switching cycle to provide inherent cycle-by-cycle current limiting and superior transient load response compared to voltage-mode control.

What is the maximum switching frequency of the UCC3807D-1G4?

The UCC3807D-1G4 can operate at switching frequencies up to 1000 kHz (1 MHz), enabling the design of power converters with very small passive components such as transformers and capacitors, which reduces overall solution size and weight.

What are the input voltage requirements for the UCC3807D-1G4?

The UCC3807D-1G4 requires an input voltage between 7.5V (minimum) and 12V (maximum), with a nominal operating voltage of 10V, making it well-suited for power supplies derived from standard 12V rails found in telecom and industrial equipment.

What package does the UCC3807D-1G4 come in?

The UCC3807D-1G4 is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package with JESD-30 code R-PDSO-G8, a compact surface-mount format that is easy to place and solder on standard PCB designs.

Is the UCC3807D-1G4 suitable for flyback converter designs?

Yes, the UCC3807D-1G4 is well-suited for flyback, forward, and boost converter topologies. Its current-mode control with 1A gate drive output allows it to directly switch power MOSFETs in isolated and non-isolated SMPS designs up to moderate power levels.
