Introduction

The S-13R1E23-M5T1U3 is a PMIC with a voltage regulator linear, a type of voltage regulator which uses a negative feedback in order to maintain a constant voltage output, despite input voltage fluctuations. It is capable of regulating the voltage of an input voltages up to 24V. This product is designed for applications in various markets, most notably automotive and industrial markets.

Applications

The S-13R1E23-M5T1U3 is designed for applications where a potentially wide input voltage range is required. It is particularly suited to automotive applications, where a wide range of input voltages (from ~9V to ~24V) are the norm. The highly efficient design makes it ideal for industrial applications; for instance, it is well suited for use in applications where there is high temperature fluctuation, as it dissipates little heat and can handle high working temperatures. It is also used to regulate the voltage in applications that require low output noise, such as audio amplifiers or sensitive communications devices.

Features

The S-13R1E23-M5T1U3 includes a few key features that make it suitable for use in a variety of applications. Its low output ripple rating means that it can produce clean and stable voltages. Its wide range of short circuit protection and overtemperature protection can prevent damage to the unit and the system in which it is installed. It includes bond-wire programming, which can be used to adjust the output voltage from a wide range (1.8V to 26V). This makes it suitable for a range of applications. Additionally, the 185kHz switching frequency allows for a high level of efficiency and fast system response.

Working Principle

The S-13R1E23-M5T1U3 uses a negative feedback mechanism to control the output voltage. It has an input voltage sensing circuit, which contains a voltage divider and an amplifier. This circuit is used to sense the input voltage, and provide an accurate representation of it to an error amplifier. The error amplifier compares this voltage to a reference voltage, and produces an error signal depending on the difference between the two. This error signal is then inputted into a pulse width modulation (PWM) controller, which produces pulses that are used to control the power switch. The power switch is used to regulate the output voltage; when the voltage is below the reference voltage, the switch will be on for an extended period of time, and when it is above the reference voltage, the switch will be off for an extended period of time.

Conclusion

The S-13R1E23-M5T1U3 is a PMIC with a voltage regulator linear, designed for a variety of applications in the automotive and industrial markets. It features a wide range of adjustable output voltage, low output ripple, and a 185kHz switching frequency for efficient operation. It uses a negative feedback mechanism to ensure that the output voltage remains constant even when there are fluctuations in the input voltage.
