The UC3843BVDR2 from On Semiconductor is a fixed-frequency, current-mode controller designed for efficient Off-Line and DC-DC converter applications. This integrated circuit 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 frequency capability of up to 500kHz. It supports Boost and Flyback topologies and provides a transistor driver output. The device operates within a temperature range of -40°C to 105°C (TA).
Packaged in a 14-SOIC (0.154", 3.90mm Width) surface-mount package, the UC3843BVDR2 is suitable for various power management designs. Protective features include undervoltage lockouts with hysteresis and cycle-by-cycle current limiting, making it a robust choice for demanding applications.
