The MC34166T is a high-performance DC-DC switching regulator designed for step-down and voltage-inverting applications. It features a fixed frequency oscillator operating at 72 kHz, capable of delivering an output switch current exceeding 3.0 A. The device includes an internal temperature-compensated reference, a latching pulse width modulator, and a high-gain error amplifier, which contribute to its efficiency and reliability. Key protective features include cycle-by-cycle current limiting, undervoltage lockout with hysteresis, and thermal shutdown. The MC34166T 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. It is available in both TO-220 and D2PAK packages, with moisture sensitivity level (MSL) rated at 1 and options for Pb-free packaging. The operating temperature range is from 0¬8C to +70¬8C, making it suitable for various applications.
