SEC115 Error Amplifier IC – Precision Voltage Regulator for TVs

Product Overview

The SEC115 is an essential part of the ‘Self-Correction’ system in electronic power boards. In many CRT and LED TVs, the power supply must remain at a very specific level (e.g., 115V) to prevent damaging the sensitive motherboard. The SEC115 acts as a ‘comparator,’ instantly telling the power supply to adjust its switching frequency if the voltage varies. This chip is a standard replacement part for technicians dealing with ‘B+’ voltage issues.

Key Features

• Precision Voltage Feedback: Maintains a steady output for TV chassis.
• 3-Pin Simple Design: Easy to test and replace on standard boards.
• High Reliability: Built for continuous operation in consumer electronics.
• Accurate Reference: Features a stable internal voltage reference.

Benefits

Replacing a drifting or faulty SEC115 can prevent the total destruction of a TV’s mainboard. It ensures that the power supply doesn’t ‘run away’ and output dangerously high voltages. For repair professionals, this IC is the primary tool for calibrating the output of a repaired SMPS. It provides a reliable, plug-and-play solution for voltage regulation.

Frequently Asked Questions

Q: My TV voltage is too high (150V+); is this the problem?
A: If the feedback loop is broken, the voltage can spike. The SEC115 is the most likely failure point in the regulation circuit.
Q: Is there a difference between SEC115 and SE110?
A: Yes, the number indicates the target voltage. SEC115 is for 115V lines, whereas SE110 is for 110V lines. Always match the number on your original part.
