UC2525AJ

DC DC Switching Controllers Overview

The UC2525AJ is a regulating pulse width modulator from the UC2525A series, manufactured by Texas Instruments. It operates within an input voltage range of 8 V to 35 V and features a 5.1 V reference trimmed to 1% accuracy. The device supports multiple converter topologies including Boost, Flyback, Forward, Full Bridge, Half Bridge, and Push-Pull. It offers an oscillator frequency range of 100 Hz to 500 kHz with a separate sync terminal. The maximum duty cycle is limited to 50%, and it includes adjustable dead-time control. The component is housed in a 16-CDIP package and functions within a temperature range of -25°C to +85°C.

DC DC Switching Controllers Feature Summary

• Supports versatile power conversion topologies such as push-pull, half-bridge, full-bridge, forward, flyback, and boost configurations.
• Features a separate oscillator synchronization terminal for external clock alignment.
• Includes adjustable dead-time control to optimize switching efficiency and prevent shoot-through.

DC DC Switching Controllers Applications

• Push-pull DC-DC converter designs
• Half-bridge and full-bridge power supply circuits
• Forward converter applications requiring precise duty cycle control

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'AJ' corresponds to the ceramic DIP package variant when sourcing. Confirm the operating temperature range requirements align with the -25°C to +85°C specification. Ensure compatibility with the 8 V to 35 V supply voltage limits for your target circuit design before finalizing procurement.

DC DC Switching Controllers Selection Notes

Select this component when a dual-output capable PWM controller supporting multiple bridge topologies is required. The UC2525AJ provides a stable 5.1 V reference and allows for external oscillator synchronization. Consider the through-hole CDIP packaging constraints and the 50% maximum duty cycle limitation during system architecture planning.

DC DC Switching Controllers Part Context

The UC2525AJ belongs to the UC2525A family of regulating pulse width modulators. This series is designed for high-performance power management applications requiring flexible topology support. The AJ suffix typically denotes the military-grade or extended temperature variant in ceramic DIP packaging, distinguishing it from plastic surface-mount alternatives like the ADW.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include other UC2525A variants such as UC2525AN or UC2525ADW, provided pinout and package compatibility are verified. Cross-referencing with UC2526 series devices may be necessary if different output counts or frequency ranges are acceptable.
