S-8357H50MC-NNJT2G

Introduction

The S-8357H50MC-NNJT2G DC DC switching controller is a PMIC (Power Management Integrated Circuit) voltage regulator suitable for a variety of applications. It provides a low dropout (LDO) voltage regulator and a switching (step down) regulator in a single 0.5mm pitch, 8-pin package. This type of regulator is useful when a user requires an efficient and reliable power supply, especially when there are various input voltages and/or multiple output voltages needed.

Application Field

The S-8357H50MC-NNJT2G DC DC switching controller operates in the variable input voltage range of 2.6V to 6V. This wide range of voltage makes it extremely suitable for use in portable electronics such as mobile phones, tablet PCs and digital cameras, where the voltage range should be various owing to the various power sources available. In addition, the regulator has a very low standby current consumption of 3µA due to its high-efficiency LDO mode. This low standby current consumption is critical when using the regulator in battery-powered systems as battery life will be improved significantly.

The S-8357H50MC-NNJT2G DC DC switching controller is also suitable for automotive applications as it can provide an output voltage of up to 5.5V with a minimum input voltage of 2.6V. This feature is quite useful for automotive applications, for example, for driving car radios which is often powered by multiple power sources with different voltage levels. Moreover, the S- 8357H50MC-NNJT2G can provide accurate and reliable voltage levels even when the input voltage is varying rapidly. Therefore, this regulator can be used in applications where a stable voltage supply is highly required.

Working Principle

The S-8357H50MC-NNJT2G DC DC switching controller features a Voltage Mode Buck-Boost (VM BB) architecture, allowing it to step up or down the input voltage to achieve the target output voltage without additional components. It is capable of a programmable precision output voltage to within 1% of the set voltage level, making it suitable for a variety of applications.

When the input voltage is higher than the target output voltage, the controller steps the input voltage down to the desired output voltage. On the other hand, if the input voltage is lower than the target output voltage, the controller will steps the input voltage up for delivering the desired output voltage. This Buck-Boost capability of S-8357H50MC-NNJT2G makes it highly suitable for applications which demand wide input voltage range and high output voltage accuracy.

Moreover, the S-8357H50MC-NNJT2G DC DC switching controller features an adjustable, low-ripple PWM (Pulse Width Modulator) mode supports. This allows it to achieve the maximum possible conversion efficiency across the entire input voltage range. In addition, the regulator includes an over-temperature protection (OTP) circuit, which provides protection against over temperature conditions and prevents damage to the device.

Conclusion

In conclusion, the S-8357H50MC-NNJT2G DC DC switching controller is an excellent mid-voltage LDO and switching regulator in a single package, suitable for a wide range of applications. It offers a wide input voltage range of 2.6V to 6V, programmable output voltage accuracy, high conversion efficiency and over temperature protection. Therefore, it is an ideal solution for users who need reliable and efficient power supply with different input voltages and multiple output voltages.
