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.
