Frequently Asked Questions
What is the SG2524DR used for?
The SG2524DR is a fixed-frequency PWM controller IC from Texas Instruments, designed for use in DC-DC switching power supplies such as buck, boost, and flyback converters. It integrates an oscillator, error amplifier, PWM comparator, and dual output transistors to simplify power supply design.
What is the input voltage range of the SG2524DR?
The SG2524DR operates from an input voltage of 8V to 40V, making it suitable for a wide range of industrial and commercial power supply applications. The oscillator frequency can be set up to 300kHz via an external resistor and capacitor.
What package does the SG2524DR come in?
The SG2524DR is available in a SOIC-16 (Small Outline Integrated Circuit, 16-pin) surface-mount package, which provides a compact footprint suitable for high-density PCB designs.
What are the alternatives to SG2524DR?
Compatible alternatives to the SG2524DR include the SG3524 (DIP-16 through-hole version), UC2524 (extended -40°C to 85°C industrial range), and TL494 (similar topology, widely second-sourced). All are fixed-frequency PWM controllers with comparable pin assignments and functionality.
Is the SG2524DR RoHS compliant?
Yes, the SG2524DR is RoHS compliant and lead-free. The 'D' suffix in the part number denotes the SOIC package, and Texas Instruments ships this part in a tape-and-reel carrier suitable for automated SMT assembly.
