onsemi PMIC - PMIC - Voltage Regulators - DCDC Switching Regulators - MC33163DWG MC33163DWG

The MC33163DWG is a monolithic power switching regulator designed for DC-DC conversion in step-up, step-down, and inverting applications. It supports an input voltage range from 2.5 V to 40 V and can deliver an output switch current exceeding 3.0 A. The device features a controlled duty cycle oscillator, two high-gain voltage feedback comparators, and a temperature-compensated reference, all aimed at minimizing the number of external components required. Key protective features include cycle-by-cycle current limiting and internal thermal shutdown, enhancing reliability in various applications. The MC33163DWG also incorporates a low voltage indicator output, facilitating direct interfacing with microprocessor-based systems. It is housed in a 16-pin dual-in-line heat tab plastic package, which improves thermal conduction. The device operates within a temperature range of 0°C to +70°C and has a moisture sensitivity level of 1. Pb-free packaging options are available.
