The UC3844N from ON Semiconductor is a versatile current-mode Pulse Width Modulation (PWM) controller. It is engineered for efficiency in offline and DC-to-DC converter designs, requiring minimal external components. This controller operates within a supply voltage range of 10V to 30V and supports frequencies up to 500kHz.
Key electrical features include a maximum duty cycle of 48% and an output type described as Transistor Driver. The device is suitable for topologies such as Boost and Flyback converters. It is housed in an 8-DIP package, designed for through-hole mounting.
The operating temperature range for the UC3844N is 0°C to 70°C (TA). Its robust design includes features like UVLO with hysteresis and a temperature-compensated reference, contributing to stable operation in various conditions. The controller is also noted for its low startup current.
This component is ideal for power supply designs where precise control and minimal component count are critical. Its through-hole package facilitates integration into many PCB layouts.
