MC34163DWR2G Description

Short technical summary and product information.

The MC34163DWR2G from On Semiconductor is a monolithic power switching regulator designed for DC-to-DC conversion. It integrates essential functions for step-up, step-down, and voltage-inverting circuits, minimizing the need for external components. This device features two high-gain voltage feedback comparators, a temperature-compensated reference, and a controlled duty cycle oscillator.

 

Key electrical characteristics include an output switch current capability of 3.4A and an operating input voltage range from 2.5V to 40V. The output is adjustable, and the topology supports both buck and boost configurations. It operates at a frequency of 50kHz and includes cycle-by-cycle current limiting and internal thermal shutdown protection.

 

Packaged in a 16-pin SOIC (0.295" width) with a surface mount type, the MC34163DWR2G is suitable for various applications requiring efficient power conversion. The operating temperature range is 0°C to 70°C (TA). Protective features and a low voltage indicator output for microprocessor interfacing are also included.
