The UC3841N from Texas Instruments is a programmable, off-line PWM controller. It supports multiple topologies such as Boost, Buck, Buck boost, Flyback, and Forward converters, operating in peak current mode.
This controller features a fixed frequency of 500kHz and a maximum duty cycle of 95%. It includes essential control features like current limit, enable, frequency control, ramp, reset, and soft start. The operating voltage range is from 8V to 32V, with an operating temperature range of 0°C to 70°C.
Designed for through-hole mounting, the UC3841N comes in an 18-PDIP package. It is suitable for applications requiring efficient power conversion in a compact form factor. Note that this product is not recommended for new designs.
Key electrical characteristics include a 1A peak current capability and 1% reference accuracy. The output type is a transistor driver, configurable for positive or isolation-capable outputs.
