The MC33166D2TR4G 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 3.0 A. The device operates within a voltage range of 7.5 V to 40 V and provides a precision output voltage of 5.05 V without the need for an external resistor divider. Key protective features include cycle-by-cycle current limiting, undervoltage lockout with hysteresis, and thermal shutdown, ensuring reliable operation under various conditions. The regulator also incorporates a low power standby mode that reduces supply current to 36 µA. It is available in a D2PAK surface mount package, making it suitable for compact designs. The MC33166D2TR4G is Pb-free and has a moisture sensitivity level of 1, indicating its robustness for various applications.
