DC DC Switching Controllers datasheet and documents for UCC28C41DR

UCC28C41DR

DC DC Switching Controllers Overview

The UCC28C41DR is a BiCMOS low-power current-mode PWM controller designed for DC-DC switching applications. It supports Boost, Flyback, and Forward topologies with a single output configuration. The device operates within a supply voltage range of 6.6V to 18V and delivers up to 1A output current. It features a maximum switching frequency of 1MHz and a maximum duty cycle of 48%. The component functions reliably across an operating temperature range of -40°C to +105°C and is housed in an 8-SOIC surface-mount package.

DC DC Switching Controllers Feature Summary

Implements current-mode PWM control architecture for efficient power management
Utilizes BiCMOS technology to achieve low quiescent power consumption
Provides rail-to-rail transistor driver outputs for direct switch control

DC DC Switching Controllers Applications

Boost converter circuits
Flyback transformer-based isolated power supplies

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'DR' corresponds to the standard tape-and-reel packaging format intended for automated assembly processes. Confirm that the 8-SOIC footprint matches the target PCB layout dimensions. Ensure the selected variant meets the required thermal dissipation capabilities for the intended operating environment without additional heatsinking measures.

DC DC Switching Controllers Selection Notes

Select this component when designing non-isolated or isolated converters requiring high efficiency at moderate power levels. The 1MHz switching capability allows for reduced passive component sizes compared to lower-frequency alternatives. Consider the 48% duty cycle limit when selecting input-output voltage ratios to ensure stable regulation under all load conditions.

DC DC Switching Controllers Part Context

This part belongs to the UCC28C4x series of automotive-grade compatible controllers. It serves as a cost-effective solution for general-purpose power conversion tasks where size and power efficiency are critical constraints. The series offers pin-compatible options for varying duty cycle and topology requirements within the same package family.
