UC2524DWTR

DC DC Switching Controllers Overview

The UC2524DWTR is an advanced regulating pulse width modulator manufactured by Texas Instruments, designed for versatile power conversion applications. It supports multiple topologies including Boost, Flyback, Forward, Full Bridge, Half Bridge, and Push-Pull configurations. The device features a fixed switching frequency of 500 kHz and provides two independent outputs with a maximum duty cycle of 45%. It operates within a supply voltage range of 8V to 40V and delivers up to 200 mA output current at 60 V. The component functions reliably across an industrial temperature range from -40°C to +85°C and is housed in a 16-pin SOIC package.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for the SOIC-16 package. Confirm that the operating temperature range meets system requirements. Check for any recent product change notices or lifecycle status updates directly from the manufacturer before finalizing procurement decisions.

DC DC Switching Controllers Selection Notes

Select this component when designing circuits requiring dual-output PWM control with support for various isolated and non-isolated topologies. Consider the 500 kHz switching frequency for balancing efficiency and component size. Evaluate the 45% maximum duty cycle constraint against input-to-output voltage ratios. Ensure the 200 mA drive capability suffices for the intended gate driver loads without external buffering.

DC DC Switching Controllers Part Context

This part belongs to the UC2524A series of advanced regulating pulse width modulators from Texas Instruments. It shares functional similarities with other members like the UC3524ADWTR but differs in specific electrical parameters such as switching frequency and temperature ranges. The series is widely used in general-purpose power supply designs requiring robust regulation and multiple topology support.
