PMIC - Voltage Regulators - Linear

The S-1335D16-N4T1U3 voltage regulator is a linear, pulse width modulation (PWM) integrated circuit (IC) that offers the user a wide range of control options. The comprehensive feature set of the S-1335D16-N4T1U3 also includes an adjustable slew rate, current limit protection, overvoltage protection, and integrated over-temperature protection. Its highly accurate output voltage, low noise, and excellent stability performance make it a desirable choice in a wide range of applications, including automotive, industrial, and consumer electronics.

Functionality

This PWM IC offers the user a number of features, including adjustable output voltage, current limit protection, and overvoltage protection. The adjustable output voltage is adjusted by setting the resistance of an external resistor. The current limit protection is set by setting a separate external resistor and can be adjusted over a wide range. Once set, the current will automatically shut down the output if it exceeds the set limit. The overvoltage protection feature protects the system from excessive output voltages by sensing and limiting the output voltage accordingly.

The S-1335D16-N4T1U3 is an ideal choice in a wide range of voltage regulation applications. It is suitable for use in DC/DC applications such as voltage step-up or step-down processes, as well as for use in battery-based power supplies and systems. It can also be used in voltage regulation systems that require AC input, such as those found in industrial equipment, data centers, and consumer electronics.The IC is available in a small SOP-8 guide punched package, making it suitable for use in space-restricted designs where space is at a premium. The S-1335D16-N4T1U3 has a high switching frequency, which can reduce the sizes of external components such as inductors, capacitors, and transformers.

Working Principle

The S-1335D16-N4T1U3 is a bidirectional linear regulator which operates on a pulse width modulation (PWM) principle. This principle works by switching two transistors at a fixed frequency to create a waveform. The waveform is then compared against a reference voltage, which is set by an external resistor, and the output is regulated accordingly.The PWM waveform is then amplified by a totem pole amplifier. The amplified waveform is then compared against the reference voltage and the output voltage is adjusted accordingly. This comparison and adjustment process continues until the output voltage matches the reference voltage.The S-1335D16-N4T1U3 incorporates a slew rate control system which allows the user to adjust the output voltage regulation range. This slew rate control system is adjustable over a wide range, making it suitable for different applications. The current limit is also adjustable, and when set, the output voltage will be shut down if the current exceeds the set limit.

Conclusion

The S-1335D16-N4T1U3 voltage regulator is a linear, pulse width modulation (PWM) integrated circuit that provides a wide range of control and regulation options. Its highly accurate output voltage, low noise, and excellent stability performance make it a desirable choice in a wide range of voltage regulation applications, including automotive, industrial, and consumer electronics. It is available in a small SOP-8 guide punched package, making it suitable for use in space-restricted designs where space is at a premium.
