The MIC23153YMT-TR is a 3A low-noise high-efficiency synchronous step-down DC-DC regulator with features including output voltage accuracy of ±2.5%, integrated MOSFETs, low-voltage soft start, and adjustable current-limit. It is a device packaged by Microchip and belongs to the family of DC to DC switching regulators within power management ICs (PMICs).A DC-DC regulator basically converts an input voltage to a desired output voltage, maintaining the output at a consistent level and efficiently providing the requirements needed for the connected load. This type of regulator generally consists of an input rectifier, inductor, and output voltage regulation circuit. The MIC23153YMT-TR is a buck converter—a common type of DC-DC regulator, which produces a regulated output voltage from a higher input voltage, reducing the power from the input source. This synchronous regulator uses internal MOSFETs to deliver a higher current efficiency than a typical linear regulator and is available in a variety of package options, including TSSOP-16 and QFN-12.In terms of device design, the MIC23153YMT-TR can integrate two series N-channel MOSFETs that switch the load at the same frequency. It includes an internal frequency oscillator and clock generator to operate at a fixed frequency of 1.2MHz. Additionally, it contains current-sense, True Soft-Start, and Low-voltage soft-start circuits.The MIC23153YMT-TR also has some of the features that can be programmed through the I2C interface and they are as follows:• Output voltage: Output voltage can be programmed from 0.6V to 3.6V in 20mV increments• Output current limit: The output current limit can be programmed to 400mA to 3A (nominal) with a maximum of 3.5A• Switching frequency: The switching frequency can be stepped up or down, ranging from 500kHz to 2MHz• Soft start: The soft start period can be programmed from 10µs to 1520µsThe MIC23153YMT-TR can be used in a variety of applications, including, but not limited to, portable devices, computers, and automotive applications. Its low quiescent current, high efficiency, and wide output voltage range make it suitable for use in the above mentioned applications.Overall, the MIC23153YMT-TR is a low-noise, high-efficiency synchronous step-down DC-DC regulator with features including output voltage accuracy of ±2.5%, integrated MOSFETs, low-voltage soft start, and adjustable current-limit. It is a device packaged by Microchip and belongs to the family of DC to DC switching regulators within power management ICs (PMICs).
