UCC2805QDRQ1

Overview

The UCC2805QDRQ1 is a low-power BiCMOS current-mode PWM controller designed for automotive applications. It supports multiple topologies including boost, flyback, and forward converters. The device operates with a switching frequency of 1 MHz and provides a maximum duty cycle of 50%. It features a single output capable of sourcing 1 A of drive current. The component functions within an operating temperature range from -40°C to +125°C and is housed in an SOIC-8 surface-mount package.

Feature Summary

Automotive-grade reliability compliant with AEC-Q100 standards
Low-power BiCMOS technology for efficient operation
Current-mode control architecture for stable regulation

Applications

Automotive power supply systems
Boost converter circuits
Flyback transformer designs
Forward converter implementations

Procurement Notes

Verify the Q suffix indicates automotive qualification and the DRQ1 suffix specifies the SOIC-8 package variant. Confirm that the component meets specific AEC-Q100 grade requirements for your target application environment. Ensure compatibility with existing design specifications before finalizing procurement orders.

Selection Notes

Select this controller for designs requiring high-frequency operation at 1 MHz with minimal quiescent current. It is suitable for space-constrained automotive electronics needing robust performance across wide temperature ranges. Consider its 50% duty cycle limit when designing feedback loops for step-up or isolated topologies.

Part Context

This part belongs to the UCC280x-Q1 family of low-power current-mode PWM controllers. These devices are engineered specifically for harsh automotive environments. They offer a balance of performance and power efficiency, making them ideal for various DC-DC conversion tasks in vehicle electrical systems.
