The UC2843BNG from ON Semiconductor is a fixed-frequency, current-mode controller designed for efficient Off-Line and DC-DC converter applications. It offers a cost-effective solution with minimal external components, featuring a trimmed oscillator for precise duty cycle control and a temperature-compensated reference.
Key electrical specifications include an operating voltage range of 7.6V to 30V, a maximum duty cycle of 96%, and a switching frequency capability of up to 500kHz. The device also includes undervoltage lockout thresholds of 8.5V (on) and 7.6V (off), making it suitable for lower voltage applications.
This controller is housed in an 8-PDIP package and supports through-hole mounting. It is designed for applications requiring boost, flyback, or step-up/step-down conversion topologies. The integrated features, such as cycle-by-cycle current limiting and programmable output deadtime, enhance its utility in power management designs.
