The MC33167THG is a high-performance DC-DC switching regulator designed for step-up and step-down applications. It features a fixed frequency oscillator operating at 72 kHz and can deliver an output switch current exceeding 5.0 A. The device includes an internal temperature-compensated reference, a high-gain error amplifier, and a latching pulse width modulator, which allows for efficient voltage regulation with minimal external components. Key protective features include cycle-by-cycle current limiting, undervoltage lockout with hysteresis, and thermal shutdown, ensuring reliable operation under various conditions. The regulator operates within a voltage range of 7.5 V to 40 V and offers a low power standby mode that reduces supply current to 36 µA. The MC33167THG is available in a TO-220 package, making it suitable for applications requiring a robust thermal performance. Its moisture sensitivity level is rated at 1, and it is available in lead-free options.
