The UC3845BD1G from ON Semiconductor is a versatile current mode controller designed for efficient off-line and DC-DC converter applications. This integrated circuit features a trimmed oscillator for precise frequency control, guaranteeing operation at 250 kHz and supporting output switching frequencies up to 500 kHz. It is suitable for boost and flyback topologies, offering a voltage input range from 7.6V to 30V.
The controller includes essential features such as a high-gain error amplifier, current sensing comparator, and a high-current totem pole output, ideal for driving power MOSFETs. Protective features include undervoltage lockouts with hysteresis, cycle-by-cycle current limiting, and adjustable output deadtime from 50% to 70%. The UC3845BD1G is available in an 8-SOIC package, designed for surface mounting.
This device is well-suited for applications requiring cost-effective solutions with minimal external components. Its robust design and integrated features make it a reliable choice for power supply designs. The operating temperature range is 0°C to 70°C (TA).
