onsemi PMIC - PMIC - Voltage Regulators - DCDC Switching Regulators - MC33163PG MC33163PG

The MC33163PG is a monolithic power switching regulator designed for DC-to-DC conversion in step-up, step-down, and voltage-inverting applications. It supports an output switch current of up to 3.4 A and operates with input voltages ranging from 2.5 V to 40 V. The device features a controlled duty cycle oscillator, two high-gain voltage feedback comparators, and a temperature-compensated reference, which contribute to its efficiency and performance. 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 for direct interfacing with microprocessor-based systems. The MC33163PG is housed in a 16-pin dual-in-line package with a heat tab for improved thermal conduction, making it suitable for applications requiring efficient thermal management. The device is also available in a Pb-free package option.
