The MIC2179-5.0BSM-TR is a high performance synchronous DC-DC boost switching regulator. It features a wide input voltage range, a 3A peak switch current, a programmable output voltage, and low RDS(ON) internal switches. An external pull-up supply voltage is not required, as it can be supplied through the IC\'s internal means.

The MIC2179-5.0BSM-TR’s main application field is to step up an input voltage in a range of 0.9V to 4.5V to the range of 2.5V to 5.5V needed to power logic and digital circuits. This voltage regulator provides an adjustable output voltage with a tight ±2% accuracy over line and load changes. The output voltage is adjustable using an external resistor divider. The MIC2179-5.0BSM-TR also utilizes pulse skip mode, making it ideal for applications that require low ripple and high efficiency.

The MIC2179-5.0BSM-TR operates by changing the inductor current between its two switches (low and high) to define the needed input voltage for the output. When the MIC2179-5.0BSM-TR’s input voltage reaches the set point, the integrated switch turns on and connects the input voltage source to the switched point of the circuit (which is usually the capacitor). The capacitor will then start to charge, and the voltage at the switched point will start to rise. When the voltage on the cap exceeds the regulated output voltage, the switch turns off and the inductor current transfers to the output capacitor.

The MIC2179-5.0BSM-TR can be synchronised to an external frequency. This prevents possible sub-harmonic oscillations when using certain components. It also supports a variety of output voltages, making it very versatile. Additionally, it features cycle-by-cycle over-current protection and an internal soft-start, which greatly reduces start-up current surges.

The MIC2179-5.0BSM-TR is a cost-effective and efficient DC-DC boost switching regulator. This IC provides up to 3A current in a small 5-pin TSOP package. Its wide input voltage range, adjustable output voltage, and low RDS(ON) switches make it an ideal solution for many applications.

In summary, the MIC2179-5.0BSM-TR is a DC-DC switching regulator which belongs to the PMIC Voltage Regulators category. It can be used for stepping up an input voltage in a range of 0.9V to 4.5V to the range of 2.5V to 5.5V needed to power logic and digital circuits. It has a wide input voltage range, adjustable output voltage, low RDS(ON) switches, and cycle-by-cycle over-current protection, making it a cost-effective and efficient solution for many applications.
