MIC38C42-1YM

PMIC - AC DC Converters, Offline Switchers

The MIC38C42-1YM is an integrated switching regulator powered by current-mode control. This type of switching regulator is used for a variety of applications found in electronics and automotive industries. This device has 3 main primary functions; voltage regulation, power conversion, and standby switching.

The MIC38C42-1YM is designed with an operating range voltage from 5V to 50V, with a current of 8 Amps. It features up to 95% efficiency, along with an integrated under-voltage lock-out protection and zero-current detection. This device also features fault protection, with integrated thermal protection, as well as reverse current protection. This device also supports both low voltage and high voltage operation.

In terms of its operational design, this device works according to the principle of current mode control, which is a single stage process. In this mode, the current through the switching FET is regulated, while the output voltage on the output is maintained. It works by sensing the output voltage with the help of a voltage sense amplifier, which in turn drives the top-side FET at the output. By regulating the voltage signal, the output voltage is maintained at a stable value.

In terms of its application fields, this device is suitable for a variety of voltage conversion and stabilizing applications. This includes applications such as DC-DC converters, offline switchers, regulated power supplies, automotive electronics and solar energy systems. Particularly in the area of automotive systems, this device is used in applications such as battery chargers, power inverters and power assist chargers.

The MIC38C42-1YM is also well suited for use in many power conditioning and power conversion systems used in large scale commercial or industrial applications. It works pretty much in the same way as for automotive applications, by regulating the current through the switching FET. Apart from its use in large industrial and commercial applications, this device is also used for applications such as portable chargers, load switching, and power supplies.

The MIC38C42-1YM device is an ideal choice for applications requiring high efficiency along with low output ripple. Additionally, the device is suitable for both low voltage and high voltage operations, and is also very cost effective, making it a very versatile power conversion device.
