What are the key features of UCC2801PWG4?

Current-mode PWM control up to 1000 kHz enabling compact, high-efficiency switched-mode power supply designs
1 A peak gate drive output for direct drive of power MOSFETs without external buffer stage in low-power converters
Programmable oscillator with soft-start and slope compensation for stable operation across wide load and line conditions

What is UCC2801PWG4 used for?

The UCC2801PWG4 is ideal for designing compact flyback, boost, and forward converter topologies in AC-DC and DC-DC power supplies. It serves telecom power modules, industrial power adapters, and battery charger circuits requiring precise current-mode control. The controller also suits auxiliary power stages in motor drives and UPS systems where high switching frequency enables reduced magnetics size.

Frequently Asked Questions

What control topology does the UCC2801PWG4 use?

The UCC2801PWG4 employs peak current-mode control with pulse width modulation, providing inherent cycle-by-cycle overcurrent limiting, fast dynamic response, and simplified loop compensation compared to voltage-mode controllers in SMPS designs.

What is the maximum switching frequency of the UCC2801PWG4?

The UCC2801PWG4 supports switching frequencies up to 1000 kHz (1 MHz), allowing use of smaller inductors and capacitors in the power stage, which reduces overall power supply size and cost in space-constrained applications.

What package does the UCC2801PWG4 come in and what is the input voltage range?

The UCC2801PWG4 is packaged in an 8-pin TSSOP with an operating input voltage range of 8.2 V to 12 V (nominal 10 V VCC), making it compatible with standard bias supply rails commonly found in SMPS auxiliary power circuits.

What protection features does the UCC2801PWG4 include?

The controller features programmable soft-start to limit inrush current during startup, cycle-by-cycle current limiting via the current sense input, and undervoltage lockout (UVLO) to prevent operation below the minimum supply threshold of 8.2 V.
