MC34163DWR2G

The MC34163DWR2G (MC34163) is a monolithic integrated circuit (IC) in a very small 8-pin surface-mountable package, making it ideal for use in a wide range of applications. It can help simplify design and reduce development time, as well as save on costs.

The MC34163 is a DC-DC switching regulator that can be used to produce output voltages from 0.5V to the input voltage rating of the IC. It enables the circuit designer to use a single device to generate multiple voltage level outputs. The MC34163 has an adjustable high frequency power oscillator, allowing a wide range of output voltage levels to be obtained in a variety of applications.

The regulatory control and protection features of the MC34163 make it suitable for a variety of applications, such as providing voltage output stages in low voltage, low noise systems, power sequencing and sequencing delays, and audio power amplifier protection.

The MC34163 is the first device to implement the many features of the new MIC31xxA family, which includes a unique 5-pin DIE control pin that can be used to control the output voltage, select between full or fixed frequency operation, and control the current limit.

The device also has a second 8-pin package option which provides access to the internal/external current limit. This version of the device can provide the most effective option for the designer to regulate the output voltage, and the flexibility of the design is further enhanced by the inclusion of an external trim potentiometer.

The MC34163 is a digitally controlled current-limited DC-DC switching regulator, designed to deliver a fixed amount of power at a nominal output voltage. The output stage is controlled by a digitally controlled voltage reference, allowing the output voltage to remain constant as the input voltage changes. The output voltage is adjustable via a trim potentiometer located on the board.

The MC34163 features thermal overload protection, output short circuit protection and over-voltage protection. In over-voltage and short circuit protection mode, the output will cease to regulate, the current will be drastically reduced and protection will be maintained.

The MC34163 can be used in a wide range of applications including: systems with multiple voltage levels, audio power amplifiers, power supplies, smart battery chargers, power sequencing and sequencing delays, motor and motor control circuits, motor drive controllers, DSPs and microprocessors, and many other power and voltage regulation applications.

The MC34163 is the ideal device for applications requiring a high performance, compact, low noise, and cost effective DC-DC converter. Its feature rich design and advanced control techniques make it a perfect fit for a variety of applications.
