UC2524N

DC DC Switching Controllers Overview

The UC2524N is a monolithic integrated circuit functioning as an advanced regulating pulse width modulator manufactured by Texas Instruments. Designed for operation within a temperature range of -25°C to 85°C, this component supports multiple converter topologies including Boost, Flyback, Forward, Full-Bridge, Half-Bridge, and Push-Pull configurations. It features two output channels with a maximum duty cycle of 50 percent. The device operates from a supply voltage of 8 V to 35 V and provides a regulated 5.1 V output capable of sourcing up to 500 mA. Switching frequencies are adjustable between 100 kHz and 500 kHz. Electrical characteristics include a rise time of 100 ns and a fall time of 50 ns. The component is housed in a 16-lead PDIP package suitable for through-hole mounting.

DC DC Switching Controllers Feature Summary

• Supports versatile power conversion topologies including push-pull, half-bridge, full-bridge, forward, flyback, and boost configurations.
• Integrates dual output drivers with independent control capabilities for complex multi-output applications.
• Features jitter-free activation through approximately 600mV hysteresis in the turn-on circuit.

DC DC Switching Controllers Applications

• High-efficiency DC-DC switching power supplies
• Industrial power management systems
• Telecommunications equipment power stages

DC DC Switching Controllers Procurement Notes

Verify the specific revision level against the manufacturer's latest documentation before integration. Confirm that the 16-lead PDIP package aligns with the target PCB footprint and thermal requirements. Ensure input voltage constraints remain within the 8 V to 35 V operational range during system design validation.

DC DC Switching Controllers Selection Notes

Select this component when designing circuits requiring flexible topology support and precise regulation. Consider the 500 mA output current capability and 50 percent maximum duty cycle limits. Evaluate the 100 kHz to 500 kHz frequency range against electromagnetic interference requirements and passive component sizing needs.

DC DC Switching Controllers Part Context

This part belongs to the UC2524 series of advanced regulating pulse width modulators. It shares functional similarities with the UC3524 but offers extended low-temperature performance down to -25°C. The series is categorized under PMIC switching controllers designed for robust industrial and commercial power applications.
