The high current capability of the MIC23201YML-T5 allows it to be used in applications with loads up to 5A.The MIC23201YML-T5 also has an internal load disconnect switch, which is invaluable for over-current or short-circuit protection. The device also provides protection against over-/under-voltage, reversed current, and over-temperature conditions.The input voltage range of the MIC23201YML-T5 is 4.5V to 30V, and the output voltage range is 0.86V to 25V. The device is designed to operate at a fixed frequency of 250kHz, which allows for optimal efficiency at low-to-medium load conditions. The MIC23201YML-T5 also has an adjustable soft-start (SS) time, which allows for an adjustable delay before full load current is applied to the output.The output voltage of the MIC23201YML-T5 can be stabilized using the integrated pulse-width modulation (PWM) current mode control loop. The PWM current mode control loop regulates the output voltage using feedback signals from an external resistor divider, with the feedback signals continuously adjusted by the integrated current mode control loop. PWM current mode control is essential for minimizing output voltage ripple and reducing power dissipation in the IC, while providing a constant, regulated output voltage.The MIC23201YML-T5 is designed to minimize the external components required to configure it. The DC-DC regulators include a power MOSFET, a linear regulator, an internal load switch, and a negative voltage generator. The voltage reference is already integrated in the IC and is therefore not required, while the output high side switch and diode are integrated. The MIC23201YML-T5 also includes internal soft-start and current limit protection, which is essential for operational safety of the device.In summary, the MIC23201YML-T5 is a high-performance synchronous step-down DC-DC converter. It is capable of providing up to 5A of load current, with an output voltage range of 0.86V to 25V. The device is designed to operate at a fixed frequency of 250kHz, with an adjustable soft-start time. The device features an internal power MOSFET, linear regulator, load switch, and voltage reference, along with additional current protection features.
