Frequently Asked Questions
What is the UC3525ADW used for?
The UC3525ADW is a programmable PWM controller used to control switch-mode power supplies including DC-DC converters, flyback, and forward topologies. It provides precise timing via its internal oscillator and 5.1V reference, making it suitable for regulated power supply designs in industrial and telecom applications.
What is the operating voltage range of UC3525ADW?
The UC3525ADW operates with a supply voltage from 8V to 35V, with an undervoltage lockout that prevents operation below the safe threshold. The internal reference is trimmed to 5.1V ±1% for accurate error amplifier feedback.
What package does UC3525ADW come in and how many pins?
The UC3525ADW comes in a SOIC-16 (Small Outline IC, 16-pin) surface-mount package. The 'DW' suffix specifically denotes the wide-body SOIC-16 format from Texas Instruments.
What are compatible alternatives to UC3525ADW?
Compatible alternatives include the UC2525ADW (industrial –40°C to 85°C grade), SG3525A (industry-standard pin-compatible PWM controller), and UC1525A (military-grade version). All share the same pinout and functional specification as the UC3525A family.
Is UC3525ADW RoHS compliant?
Yes, the UC3525ADW is RoHS compliant and lead-free. Texas Instruments ships this device in a green/Pb-free SOIC-16 package meeting EU RoHS and WEEE directives.
