What are the key features of UCC3807N-3G4?
- Current-mode PWM control at up to 1000 kHz enabling compact high-frequency power supply designs
- 1A peak gate drive output with 4.3V to 12V input voltage range for flexible topology support
- 8-pin PDIP package simplifying prototyping and hand assembly in isolated and non-isolated converters
What is UCC3807N-3G4 used for?
The UCC3807N-3G4 is used in flyback, forward, and boost converter designs for industrial power supplies, telecom equipment, and distributed power systems requiring current-mode control up to 1 MHz. Its 1A gate drive capability allows direct switching of medium-power MOSFETs without additional buffer stages, reducing design complexity. The wide 4.3V to 12V bias input range makes it adaptable to various auxiliary supply rails in offline and DC-DC converter applications.

Frequently Asked Questions
What is the maximum switching frequency and gate drive current of UCC3807N-3G4?
The UCC3807N-3G4 supports a maximum switching frequency of 1000 kHz and provides a 1A peak gate drive output, enabling high-frequency power converter topologies that reduce the size of magnetics and filter capacitors while maintaining stable current-mode control.
Which power supply topologies are best served by UCC3807N-3G4's current-mode PWM control?
Flyback, forward, and boost converters benefit most from the UCC3807N-3G4 because current-mode control inherently provides cycle-by-cycle current limiting, automatic feed-forward compensation for input voltage changes, and simplified loop compensation compared to voltage-mode control, all within a compact 8-pin PDIP package.
What input voltage range does UCC3807N-3G4 accept and how does it affect auxiliary supply design?
The UCC3807N-3G4 operates with an input voltage between 4.3V and 12V nominal, with a maximum of 12V, which allows it to be powered directly from a 5V or 12V auxiliary winding in offline power supplies without additional regulation, simplifying the overall converter architecture.
How does UCC3807N-3G4 compare to voltage-mode controllers when transient load response is critical?
Unlike voltage-mode controllers, UCC3807N-3G4's current-mode architecture senses the inductor current on every switching cycle, providing inherently faster transient response and automatic overcurrent protection without a dedicated current sense comparator, which is particularly valuable in point-of-load converters supplying processors or FPGAs with rapidly changing loads.
