UC2823AN

DC DC Switching Controllers Overview

The UC2823AN is a high-speed PWM controller manufactured by Texas Instruments, designed for switching power supply applications. It supports Boost, Buck, Flyback, and Forward topologies with two outputs. The device features a 1 MHz switching frequency and achieves a maximum duty cycle of 100%. It provides a 5.1 V output voltage and delivers up to 2 A output current. Operating within a temperature range of -40°C to +85°C, it utilizes a PDIP-16 through-hole package. Key timing characteristics include 20 ns rise and fall times.

DC DC Switching Controllers Feature Summary

• Supports multiple converter topologies including Boost, Buck, Flyback, and Forward configurations
• Enables full load regulation capability with a maximum duty cycle reaching 100 percent
• Integrates high-speed switching performance with rapid signal transition times

DC DC Switching Controllers Applications

• High-frequency DC-DC converter designs
• Flyback transformer-based power supplies
• Forward converter implementations
• Boost and Buck step-up/step-down circuits

DC DC Switching Controllers Procurement Notes

Verify the specific ordering suffix to confirm the package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your assembly process. Confirm that the PDIP-16 through-hole format aligns with your PCB manufacturing capabilities. Check for any lead-free soldering restrictions or moisture sensitivity levels before procurement.

DC DC Switching Controllers Selection Notes

Select this controller when a 1 MHz switching frequency and 100 percent duty cycle are required for precise voltage regulation. The PDIP-16 package suits prototyping or low-volume through-hole production. Consider the 2 A output drive capability for direct gate driving needs. Evaluate thermal management requirements given the specified operating temperature range.

DC DC Switching Controllers Part Context

The UC2823AN belongs to the UC2823A series of high-speed PWM controllers from Texas Instruments. It serves as a core component in power management integrated circuits (PMIC) for efficient energy conversion. The device complements other variants like the UC2825AN, differing primarily in duty cycle limits and output configurations within the same functional family.
