概要 UC3825N

The UC3825N is a pulse width modulation (PWM) controller IC designed for regulating power in switched-mode power supplies. It operates with a wide input voltage range and is capable of driving high current MOSFETs or IGBTs. The UC3825N features on-chip PWM control circuitry for adjustable frequency and duty cycle, as well as soft-start and current limiting functions. It also includes a precision voltage reference, error amplifier, oscillator, and various protection features like overcurrent and overvoltage protection. This IC is commonly used in applications such as DC-DC converters, battery chargers, inverters, and motor control systems. It is available in a 16-pin dual in-line package (DIP) and operates over a wide temperature range.
