NJM3524D

Overview

The NJM3524D is a switching controller IC designed for multiple power supply topologies, including Buck, Boost, Flyback, and Push-Pull configurations. It supports positive output regulation and offers isolation capability. The device operates with a fixed switching frequency of 30kHz and features a maximum duty cycle of 45%. Key control functions include current limit protection. The component is housed in a 16-pin DIP package and is part of the NJM3524 series.

Feature Summary

• Supports versatile switching topologies including Buck, Boost, Flyback, and Push-Pull
• Provides current limit control features for circuit protection
• Capable of driving isolated output configurations

Applications

• Buck converter designs
• Boost converter applications
• Flyback power supply circuits
• Push-pull transformer-driven systems

Procurement Notes

Verify the specific suffix (e.g., D for DIP) to ensure correct package type. Confirm RoHS compliance status if required by project specifications. Check manufacturer documentation for detailed electrical characteristics and thermal performance data before integration.

Selection Notes

Select this component when a single controller IC needs to support multiple DC-DC conversion topologies. Consider the 30kHz fixed frequency and 45% max duty cycle constraints. Ensure the application requires current limit protection and potentially isolated outputs compatible with the specified control architecture.
