Introduction

The S-1335A16-A4T2U3 is a PMIC (Power Management IC) Voltage Regulator that belongs to Linear technologies. It is used to adjust, boost up, or diminish the supply voltage of different electrical circuits by providing an adequate regulation.

Application fields

The S-1335A16-A4T2U3 PMIC can be used in a wide range of products from small tools and devices to larger systems and even factory automation projects. It is suitable for 3.3 /3.2 Vcc power supply and for most voltage requirements between 5V and 30V. These features make it a good fit for devices that must sustain high-voltage or high-frequency work.It can be used in diodes, micro-controllers, clocks, boards, RAM and Flash memory applications. It has a wide range of uses in industrial tasks, such as the regulation of motor voltages and the control of adjustable voltage and current sources.

Features

The S-1335A16-A4T2U3 PMIC presents several interesting features: • High-frequency step down switching regulator: it allows up to 1.2A of output current. • High-input voltage: it supports up to 35V, which is suitable for most high-voltage requirements. • Extrac exernal pcb mount: it allows more flexibility when designing the board. • Adaptive on-time control: it reduces the response times to changes in output load. • Constant-frequency operation: it ensures that the switching frequency is regulated and kept constant, even under high loads.• PWM to Pulse Width Modulation: it enables effective power control. • Built-in driver: it simplifies the development of the control system. • Low no-load power consumption: it helps to save energy when the device is not in use.

Working Principle

The S-1335A16-A4T2U3 operates under a switching regulator architecture. This means that it is able to adjust and regulate the input voltage into a certain range of output voltage, giving a better efficiency than a linear regulator. It uses two feedback loops in order to reach the desired output voltage and implement the adaptive on-time control. The first loop compares the voltage on the output with a reference voltage and the second compares the current on the output with a current reference.When the input voltage is higher than the predetermined voltage level, the first loop will reduce the switching frequency in order to decrease the output voltage. When the current is higher than the reference current, the second loop will reduce the amount of time the switching influence is active.These control loops work together to guarantee that the output voltage and current remain under the preset values. This provides stability and enhances the efficiency of the device.

Conclusion

The S-1335A16-A4T2U3 is an excellent solution for any project that needs a high-frequency, high-output, adjustable voltage and current regulator. Its features make it an ideal fit for a wide variety of applications, ranging from industrial to consumer projects. It is also easy to use and sets up, reducing development time and costs.
