Introduction to S-8351A22MC-J2HT2U Application Field and Working PrincipleThe S-8351A22MC-J2HT2U is a highly efficient DC-DC switching regulator that can be used to provide a stable power supply voltage in many different applications. It is part of the S-8 Series of high performance voltage regulators from Murata. This series includes regulators that are capable of regulating output voltages between 0.8 and 5.0 volts with a maximum current of really 2 A within 0.1% accuracy and with high reliability.The S-8351A22MC-J2HT2U is a step-down DC-DC switching regulator that can be used to provide a voltage stable and efficient supply of power to a wide variety of electronic systems, such as computers, consumer electronics and audio equipment. This device is capable of operating in a wide input range of 4.5 to 5.5 volts and a single output of 3.3 volts with a maximum current of 1.2A. The efficiency of the regulator is up to 94%, which makes it an ideal choice for applications where power consumption needs to be kept to a minimum.The Principle of Operation of the S-8351A22MC-J2HT2UThe S-8351A22MC-J2HT2U is based on a buck topology of dc-dc converter which includes, a low side switch, a multiple diode full-wave bridge rectifier, a current sense resistor, an error amplifier, and a PWM controller IC. The buck-topology is a type of DC-DC switching regulator which steps down the input voltage to the desired output voltage. The input voltage is applied to the multiple diode full-wave bridge rectifier where it is converted to a rectified voltage. The rectified voltage is then applied to the low side switch of the buck-topology. The low side switch is connected to the output load, the current sense resistor, and the PWM controller.The current sense voltage is fed to the PWM controller circuit and is then compared to the voltage reference set by the error amplifier to generate a PWM signal. The PWM signal is used to control the low side switch (or switch) of the dc-dc converter. The duty cycle of the PWM signal determines the voltage across the switch. When the duty cycle is low, the switch is turned off and the output voltage is equal to the input voltage. When the duty cycle is high, the switch is turned on and the output voltage is set to the voltage reference set by the error amplifier. As the duty cycle of the PWM signal increases and decreases, the output voltage is regulated accordingly. With the use of the S-8351A22MC-J2HT2U, the voltage is controlled within 0.1% of the target voltage. The high efficiency of the regulator is achieved by the combination of its buck topology and the use of synchronous rectifier which eliminates the need for an output diode, greatly reducing the power losses.Application Fields for S-8351A22MC-J2HT2UThe S-8351A22MC-J2HT2U is a highly efficient, low power regulator that is perfect for a variety of different applications.
