Working Principle

The UC3524N is designed to control switching regulators with low impedance devices, such as a MOSFET or IGBT. This device uses frequency modulation and Pulse width Modulation (PWM) to convert the voltage from an input source into a regulated output voltage or current. The device uses an internal voltage reference to maintain the output voltage or current at a desired level. The device has an internal logic circuit for direct control of a synchronous rectifier.

The UC3524N has a wide operating temperature range and is suited for use in applications where high power is required and/or high-temperature environments. The device is also well suited for use in industrial level applications where long life and reliable operation are needed. The UC3524N is provided with an internal temperature sensor which compensates the output voltage to maintain accuracy and stability.
