Texas Instruments UC3524 Advanced Regulating Pulse Width Modulators UC3524-W

The UC3524 is an advanced regulating pulse width modulator designed for use in power supply applications, including inverters and switching regulators. It features complete PWM power control circuitry and can operate in both single-ended and push-pull configurations. The device includes an on-chip reference, error amplifier, programmable oscillator, and current-limiting circuitry, making it suitable for high-power-output applications. The UC3524 operates within a temperature range of 0¬8C to 70¬8C and has a low standby current of approximately 8 mA. It is characterized for operation with a supply voltage ranging from 8V to 40V and can deliver a reference output voltage of 5V with good line and load regulation. The device is also interchangeable with similar models such as the SG3524, providing flexibility in design choices.
