Details
The UC3843AN is a highly adaptable PWM controller IC manufactured by Texas Instruments, designed for voltage mode control in switch-mode power supply applications. This IC offers precise regulation of output voltage through the integration of a precision voltage reference, error amplifier, PWM comparator, and a high-current totem-pole output stage. The internal oscillator of the UC3843AN can be adjusted across a wide frequency range, providing design flexibility. By regulating the duty cycle of the output waveform based on feedback from the output voltage, this versatile device enables efficient power conversion. With its wide input voltage range and robust design, the UC3843AN is well-suited for various power supply designs, including AC/DC converters, DC/DC converters, and battery chargers. The 'AN' suffix denotes the package type, typically a DIP (Dual Inline Package), making it suitable for through-hole mounting on PCBs
