概述

Description

UC2526ADWTR is a TI/Unitrode UC2526A pulse-width modulation (PWM) controller IC used in switch-mode power supplies. It integrates the precision reference, error amplifier, oscillator, PWM comparator, and protection features to regulate the drive to a power switch (e.g., MOSFET). By comparing feedback from the output with the internal reference, it adjusts the duty cycle to maintain the desired output voltage, and supports common SMPS topologies such as flyback, forward, buck, and boost converters. The ADWTR suffix denotes a specific packaging/reel/temperature option for the part; exact details (pinout, electrical specs, packaging) are in the UC2526ADWTR datasheet. For design guidance, refer to the TI data sheet and application notes.

Package

UC2526ADWTR is in an 8-pin Wide-SOIC (DW) package, supplied in Tape & Reel (TR) packaging.

Pinout

- Pin count: 8 pins (DIP-8/SO-8 package)
- Function: An 8-pin current-mode PWM controller for switch-mode power supplies (SMPS). It provides a 5V reference, error amplifier inputs, oscillator (RT/CT), PWM comparator, current-sense input, and an output driver with undervoltage lockout for regulating the converter’s duty cycle.

Manufacturer

Manufacturer: Texas Instruments (TI). TI is an American multinational semiconductor company that designs, manufactures, and sells integrated circuits and other electronics components. The UC2526 originates from Unitrode, whose products TI acquired; TI now markets the UC2526 as part of its power-management IC line.

Application

UC2526ADWTR is a PWM controller for switch‑mode power supplies. Typical applications include offline AC‑DC adapters and DC‑DC converters (flyback, forward, buck/boost topologies), telecom and computer power supplies, monitors, and battery chargers.
