Linear regulators are used to maintain a defined output voltage and current in a system. The S-1333D20-A4T1U3 is a 3-phase digital power switch IC for AC/DC and DC/DC applications, which integrates buck, boost, buck-boost and LCM circuit operations. It is designed to provide improved efficiency, reduced system size and more robust system operation compared to traditional power switches.

The S-1333D20-A4T1U3 is designed for wide input voltage range applications with 12 V to 48 V input voltage, hence making it suitable for a variety of input sources with different voltages. It features an inductor current sense feature, to monitor and detect excessive current, as it provides a 0.35V/A sense voltage output. It has an internal regulator to supply the gate drive level to the power switches, so external power supply is not needed. It has a synchronous rectifier enable/disable function, allowing the rectifier to be disabled when the loads are connected in parallel. It also has a built-in internal voltage feedback per phase (VFB), thus eliminating the need for external sensors.

The S-1333D20-A4T1U3 features a 3-phase modulation circuit, which works in PWM (pulse width modulation), MPM (multi-phase modulation), or a combination of both, to deliver the required output voltage or current. In PWM mode, the 3-phase circuit adjusts the on/off state of each switch, while in MPM mode, the operation of each switch is changed in a certain sequence in order to distribute the load and reduce the total device switching waveform distortion. This also helps in providing a smooth DC output.

The S-1333D20-A4T1U3 is suitable for a variety of application fields, such as motor control, telecom/datacom, server, storage, and other industrial systems. All of these equipments require different levels of voltage and current to be maintained. The S-1333D20-A4T1U3 takes care of all these requirements with its built-in high performance 3-phase modulation circuit and wide input voltage range.

The S-1333D20-A4T1U3 is a very versatile device and hence it is used in a wide range of application fields. It is designed to provide efficient and reliable system operation compared to traditional power switches, as it features a wide input voltage range, internal regulator, inductor current sense, synchronous rectifier enable/disable, and built-in voltage feedback per phase. Its 3-phase modulation circuit works in PWM or MPM mode, allowing it to deliver the required output voltage or current.
