UC2525ANG4

DC DC Switching Controllers Overview

The UC2525ANG4 is a regulating pulse width modulator manufactured by Texas Instruments, designed for versatile DC-DC switching applications. It supports multiple topologies including Boost, Flyback, Forward, Full Bridge, Half Bridge, and Push-Pull configurations. The device operates with a supply voltage range of 8 V to 35 V and features two output channels capable of sourcing up to 500 mA. It functions within a switching frequency band of 100 kHz to 500 kHz, with a maximum duty cycle of 50%. The component is housed in a 16-pin PDIP package suitable for through-hole mounting and operates reliably across an extended temperature range from -25°C to +85°C.

DC DC Switching Controllers Feature Summary

• Supports multiple converter topologies including push-pull, half-bridge, full-bridge, forward, flyback, and boost configurations
• Provides dual high-current outputs for driving external power switches
• Integrates soft-start functionality to limit inrush current during startup
• Includes clock synchronization capability for multi-controller systems

DC DC Switching Controllers Applications

• Industrial power supply designs requiring isolated or non-isolated conversion
• Telecommunications equipment power distribution units
• Server and workstation DC-DC converter modules
• Automotive electronics power management systems

DC DC Switching Controllers Procurement Notes

Verify the specific suffix G4 indicates lead-free compliance and RoHS status before procurement. Confirm the PDIP-16 package dimensions match your PCB footprint requirements. Check for obsolescence notices as this part may be discontinued or replaced by newer series components. Ensure the operating temperature range meets your environmental specifications.

DC DC Switching Controllers Selection Notes

Select this controller when multiple topology support is required within a single component. Consider the 500 mA output drive capability for direct gate driving of MOSFETs without additional buffer stages. Evaluate the 100 kHz to 500 kHz frequency range against your transformer size and efficiency targets. Compare against the UC3525ANG4 if industrial temperature range (0°C to 70°C) is sufficient for your application.

DC DC Switching Controllers Part Context

This component belongs to the UC2525A series of regulating pulse width modulators from Texas Instruments. It is part of a broader family of PMIC solutions designed for flexible power conversion architectures. The UC2525ANG4 variant specifically denotes the commercial/extended temperature grade version in a through-hole package, distinct from surface-mount alternatives like the UC2525BDWTR.

DC DC Switching Controllers Replacement Considerations

UC2525AN is listed as a manufacturer recommended substitute. UC3525ANG4 serves as a functional alternative with similar electrical characteristics but differs in operating temperature range.
