Key Features
- Configurable peak or average current-mode PWM control for flexible power supply topologies
- 9 V to 15 V input voltage range supporting standard telecom and industrial bias supplies
- 16-pin SOIC package with pulse-width modulation for high-density power converter designs
Applications
UC28025DWR is designed for regulated DC-DC power supplies in telecom base stations and industrial equipment requiring precise current-mode PWM control. Its ability to switch between peak and average current-mode control allows designers to optimize loop stability and transient response for forward converters operating at switching frequencies up to 1 MHz. The 16-pin SOIC package integrates gate drive and protection functions, reducing external component count in high-reliability power supply modules.

Frequently Asked Questions
What input voltage range does UC28025DWR support and which power supply applications does that cover?
UC28025DWR accepts input voltages from 9 V to 15 V, with a nominal operating point at 15 V, making it directly compatible with standard telecom -48 V derived bias rails and industrial 12 V auxiliary supplies. This range covers the majority of AC-DC and DC-DC converter control stage supply requirements without external regulation.
How does the UC28025DWR support both peak and average current-mode control in converter designs?
UC28025DWR can be configured for either peak current-mode or average current-mode PWM control by adjusting the external compensation network and sense resistor placement. Average current mode offers better noise immunity and more accurate current regulation for output currents above 5 A, while peak current mode enables cycle-by-cycle protection and faster transient response in converters below 200 W.
What protection features does UC28025DWR include for high-reliability power supply designs?
UC28025DWR integrates cycle-by-cycle current limiting, undervoltage lockout (UVLO) with a threshold near 9 V, and soft-start functionality to limit inrush current during startup. These protection features reduce stress on external MOSFETs and transformers, extending MTBF in 24/7 industrial and telecom power supply applications that must meet IEC 62368 safety standards.
In what package does UC28025DWR come and how does it compare to DIP alternatives for servicing?
UC28025DWR is packaged in a 16-pin SOIC (R-PDSO-G16) with 1.27 mm pin pitch, which is more compact than a through-hole 16-pin DIP by approximately 40% in board area. While SOIC requires SMT assembly, it allows denser PCB layouts and is fully compatible with standard IR reflow and wave solder profiles used in modern power converter manufacturing.
