The UC3843BD1R2G 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.
Key electrical specifications include an operating voltage range of 7.6V to 30V, a maximum duty cycle of 96%, and a switching frequency of up to 500kHz. The device supports Boost and Flyback topologies and features frequency control.
This controller is housed in an 8-SOIC surface-mount package. It operates within a temperature range of 0°C to 70°C.
The UC3843BD1R2G integrates features such as a trimmed oscillator for precise frequency control, a temperature-compensated reference, a high-gain error amplifier, and a high-current totem pole output. Protective features include undervoltage lockouts with hysteresis and cycle-by-cycle current limiting.
