MIC2179-5.0YSM-TR Application Field and Working Principle

The MIC2179-5.0YSM-TR is a DC to DC switching regulator that is part of an integrated power module package that includes voltage regulators and linear regulators. The regulator has high efficiency, low noise and excellent thermal stability. It is suitable for powering digital systems, such as those used in laptops and notebooks, as well as embedded control systems.

The MIC2179-5.0YSM-TR, like other switching regulators, operates by rapidly switching a device between two states, usually on and off, to reduce the input voltage to a desired output voltage. This type of circuit is also referred to as a pulsed width modulation, or PWM, power supply, since it is a type of pulse-width modulation. In order for the regulator to be able to switch at the required frequency and maintain constant output voltage, its control section must be provided with an accurate reference voltage. This reference voltage, known as the bias voltage, is usually derived from an external voltage source, such as a battery. This bias voltage is used to control the switching action of the regulator.

The MIC2179-5.0YSM-TR\'s switching action is based on the buck converter topology. A buck converter is a type of DC to DC converter that steps down the input voltage, turning it into a lower output voltage. This is accomplished by using a transistor switch, which is switched on and off at predetermined intervals. By varying the duty cycle of the switch, the output voltage of the regulator can be controlled. The frequency of the switching is determined by an internal oscillator, but can be adjusted using external components.

The MIC2179-5.0YSM-TR also features a linear post regulator. This section of the regulator supplies a low-noise, ripple-free output voltage, with well-controlled transient response during start-up and shut-down. The linear regulator is key for allowing the switching regulator to provide continuous operation, as it reduces the noise and instability of the output voltage.

The MIC2179-5.0YSM-TR is an ideal choice for applications that require high-efficiency and clean, low-noise outputs. Examples of such applications include powering battery-powered systems, solar and wind power systems, handhelds, and mobile devices. The device\'s efficient performance, integrated switching and linear regulation, low ripple and noise, and thermal protection make it an excellent choice for a wide range of power supply design requirements.
