The ON Semiconductor MC34067DWR2G is a versatile high-performance controller that is designed for use in a variety of power conversion applications. This device integrates all the necessary features to implement off-line or DC to DC fixed frequency current mode control schemes with minimal external components.

The MC34067DWR2G operates at a frequency range of up to 100 kHz and offers a high level of integration, resulting in a compact and efficient design. It features a trimmed oscillator for precise frequency control, a temperature-compensated reference, high gain error amplifier, current sensing comparator, and a high current totem pole output ideally suited for driving a power MOSFET.

Additionally, the device incorporates protective features such as a programmable input for setting the maximum duty cycle, a latch for single pulse metering, and an under-voltage lockout protection with hysteresis. The under-voltage lockout ensures that the device remains off unless there is a sufficient supply voltage. This feature is critical for preventing power devices from operating in unsafe conditions.

The MC34067DWR2G is housed in a 16-pin SOIC wide body package, which allows for adequate spacing and heat dissipation in high-power applications. This controller is tailored for power supplies for personal computers, office equipment, and industrial control systems where efficient power conversion is paramount.

ON Semiconductor's commitment to quality and reliability is evident in the MC34067DWR2G, making it a smart choice for designers seeking a high-performance solution for their power management needs. With its comprehensive feature set and robust design, the MC34067DWR2G is well-suited to meet the challenges of modern power conversion requirements.
