Texas Instruments 18-Pin SOIC 2-Channel Voltage Mode PWM Controller 650 kHz 35V UC3526ADW

Texas Instruments UC3526ADW is an 18-pin dual-channel voltage mode Pulse Width Modulation (PWM) controller designed for robust power management in electronic circuits. Operating at a maximum switching frequency of 650 kHz and supporting supply voltages up to 35V, this surface mount device is ideally suited for flyback converter and isolated power supply applications.

The device provides stable constant voltage and current output control to enhance transient response in power conversion. With 2 PWM outputs capable of 100 mA output current each, the UC3526ADW supports efficient power delivery while maintaining low quiescent current of 4 mA, optimizing energy usage.

Its surface-mount SOIC package with 18 pins measures 11.62mm in length, 7.52mm in width, and 2.35mm in height, enabling compact PCB layouts. The PWM controller operates reliably across the industrial temperature range of 0°C to 70°C, and its maximum duty cycle of 49% ensures accurate voltage modulation for regulated power systems.

This controller integrates primary-side regulation to eliminate the need for optocouplers, simplifying circuit design and enhancing reliability.
