DC DC Switching Controllers datasheet and documents for UCC28C45DGKR

UCC28C45DGKR

DC DC Switching Controllers Overview

The UCC28C45DGKR is a BiCMOS low-power current-mode PWM controller manufactured by Texas Instruments. It supports Boost, Flyback, and Forward topologies with a switching frequency of 1 MHz. The device operates within a supply voltage range of 7.6 V to 18 V and delivers an output current of 1 A. It features a maximum duty cycle of 50% and consumes 2.3 mA of quiescent current. The component is housed in an 8-pin VSSOP package and functions reliably across a temperature range of -40°C to +105°C.

DC DC Switching Controllers Feature Summary

Implements current-mode control architecture for efficient power management
Designed for low-power operation suitable for battery-driven applications
Supports multiple converter topologies including boost, flyback, and forward

DC DC Switching Controllers Applications

Battery-powered portable devices
Low-power AC/DC converters
Industrial control systems

DC DC Switching Controllers Procurement Notes

Verify the specific suffix DGKR confirms the VSSOP-8 tape-and-reel packaging configuration. Ensure compatibility with the required operating temperature range of -40°C to +105°C for your application environment. Confirm RoHS compliance status through official manufacturer documentation prior to integration.

DC DC Switching Controllers Selection Notes

Select this component when a 1 MHz switching frequency and 1 A drive capability are required in a compact surface-mount package. It is appropriate for designs prioritizing low quiescent current consumption. Consider alternative packages if higher thermal dissipation or different pin counts are necessary for the circuit layout.

DC DC Switching Controllers Part Context

This part belongs to the UCC28C4x series of BiCMOS low-power current-mode PWM controllers from Texas Instruments. The series provides integrated solutions for offline and DC-DC conversion applications requiring high efficiency and minimal standby power consumption in small form factors.
