UC2524ADWG4

DC DC Switching Controllers Overview

The UC2524ADWG4 is an advanced regulating pulse width modulator from Texas Instruments, designed for double-ended switching applications. It operates within a voltage range of up to 40 V and supports a switching frequency of 300 kHz. The device features a maximum duty cycle of 45% and provides two output channels with a peak current capability of 200 mA. It is housed in a 16-pin SOIC package and functions reliably across an operating temperature range of -40°C to +85°C.

DC DC Switching Controllers Feature Summary

• Supports multiple converter topologies including Boost, Flyback, Forward, Full Bridge, Half Bridge, and Push-Pull configurations.
• Includes a dedicated shutdown pin for power management control.

DC DC Switching Controllers Applications

• Industrial power supply systems
• Telecommunications equipment
• Battery chargers

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS adherence as per Texas Instruments standards. Confirm the SOIC-16 package dimensions match your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Check for moisture sensitivity level (MSL) handling requirements during assembly. Validate that the 45% maximum duty cycle aligns with your circuit design constraints.

DC DC Switching Controllers Selection Notes

Select this component when a double-ended PWM controller is required for isolated or non-isolated topologies. It is suitable for designs needing a fixed 300 kHz switching frequency. Consider the 200 mA output drive capability for direct gate driving of external MOSFETs. Compare against the UC3524A if industrial temperature ranges are not critical, or the UC2526A for different duty cycle characteristics.

DC DC Switching Controllers Part Context

This part belongs to the UC2524A series of advanced regulating pulse width modulators. It is functionally similar to the SG2524 but offers enhanced performance characteristics. The device is part of Texas Instruments' broader portfolio of power management integrated circuits, specifically targeting high-reliability switching power supply applications.

DC DC Switching Controllers Replacement Considerations

The UC2524ADWTR is a tape-and-reel variant of the same functional device. The UC2524ADW is the standard tube-packaged version without the G4 lead-free suffix. Verify pin compatibility and electrical parameters before substituting.
