UC2525AN

DC DC Switching Controllers Overview

The UC2525AN is a Texas Instruments switching controller regulating pulse width modulator designed for versatile power supply topologies. It supports Boost, Flyback, Forward, Full Bridge, Half Bridge, and Push-Pull configurations. The device features two outputs with a maximum duty cycle of 50 percent. It operates within a frequency range of 100 kHz to 400 kHz and accepts a supply voltage between 8 V and 35 V. The output stage provides 500 mA current capability at 5.1 V. It functions reliably across an ambient temperature range of -25°C to +85°C. The component is housed in a 16-pin PDIP package suitable for through-hole mounting.

DC DC Switching Controllers Feature Summary

• Supports multiple converter topologies including push-pull, half-bridge, full-bridge, forward, flyback, and boost
• Provides dual independent output channels for synchronized switching control
• Integrates soft-start functionality to manage inrush current during startup
• Includes clock synchronization capability for multi-controller systems

DC DC Switching Controllers Applications

• Industrial power supplies requiring isolated DC-DC conversion
• Telecommunications equipment power distribution units
• Server and workstation internal voltage regulation modules
• Battery charging systems utilizing push-pull or half-bridge architectures

DC DC Switching Controllers Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to confirm pinout compatibility and electrical tolerances. Ensure the procurement channel provides valid traceability records for quality assurance purposes. Confirm that the delivered components match the specified PDIP-16 package dimensions and lead finish requirements before integration into production assemblies.

DC DC Switching Controllers Selection Notes

Select this component when designing circuits requiring flexible topology support beyond standard single-output controllers. Consider the 50 percent maximum duty cycle limitation when determining transformer turns ratios for forward or push-pull designs. Evaluate the 100 kHz to 400 kHz operating range against external timing resistor and capacitor selections to achieve the desired switching frequency without exceeding thermal limits.

DC DC Switching Controllers Part Context

This part belongs to the UC2525A series of voltage-mode PWM controllers manufactured by Texas Instruments. It serves as a specialized alternative to broader family members like the UC3525 or UC2825, offering distinct electrical characteristics tailored for mid-power applications. The UC2525AN variant specifically denotes the commercial grade version packaged in a standard plastic dual in-line format for general-purpose electronic manufacturing.
