The MC33163DW is a monolithic power switching regulator designed for DC-to-DC conversion in step-up, step-down, and voltage-inverting applications. It features a maximum output switch current of 3.4 A and operates with input voltages ranging from 2.5 V to 40 V. The device includes essential components such as high gain voltage feedback comparators, a temperature-compensated reference, a controlled duty cycle oscillator, and a driver with bootstrap capability for enhanced efficiency. Key protective features include cycle-by-cycle current limiting and internal thermal shutdown, ensuring reliable operation under various conditions. Additionally, it has a low voltage indicator output that interfaces directly with microprocessor-based systems. The MC33163DW is available in a 16-pin dual-in-line heat tab plastic package, which improves thermal conduction. Its moisture sensitivity level is rated at 1, and Pb-free packaging options are available. This product is suitable for applications requiring efficient voltage regulation with minimal external components.
