The S-8351B27MA-J4MT2G is a DC DC Switching Regulator, belonging to Voltage Regulators, which is a part of Power Management IC (PMIC).
The S-8351B27MA-J4MT2G chip is a digitally-controlled single-output step-down DC/DC converter with a power supply input voltage range of up to 27V, allowing it to be used in industrial, medical, communications and consumer applications. It features an integrated regulator control loop featuring an on-chip high side FET, a low side FET, an error amplifier and a reference voltage regulator.
This device is highly efficient, offering up to 94% power efficiency, low EMI and low output voltage noise, as well as a power loss protection feature at low input voltages. It also helps reduce current consumption, as it has a variable switching frequency that can be adjusted from 250 kHz to 750 kHz.
The S-8351B27MA-J4MT2G DC/DC converter can convert a wide input voltage range of 2.3V–27V to a desired output voltage of 0.8V–20V. It has a maximum output current of 2.15A and is designed for high-speed switching applications. The device is available in a TO-263 package, and can operate up to an ambient temperature of 85°C.
The S-8351B27MA-J4MT2G operates on a typical buck DC/DC converter circuit, in which an input voltage is applied to an inductor, the output of which is filtered by an output capacitor, providing a regulated output voltage. The inductor current of the converter is switched between two levels, which is controlled by a pulse-width-modulation (PWM) signal, generated by the device.
The PWM signal is generated using the internal error amplifier, which compares the output voltage to a voltage reference and adjusts the duty cycle of the PWM signal accordingly. This ensures an accurate, stable output voltage. Additionally, the device has various functions and protection circuits built-in, such as an over current and over voltage protection, and under voltage lockout.
In summary, the S-8351B27MA-J4MT2G is an economical, reliable and efficient DC/DC switching power supply solution for industrial, medical, communications and consumer applications. It is easy to configure and can provide up to 94% efficiency. Its integrated features, such as over current and over voltage protections, and under voltage lockout, make it ideal for a wide variety of applications.
