The supply voltage for S1701B3342-U5T1G is 4.5V to 13.3V with a maximum input voltage of 13.3V, and the output voltage range is from 0.9V to 3.3V. It is designed to power a wide range of applications, including embedded computing systems that require high current output and accurate voltage regulation. It supports up to 6A of output current and is capable of delivering up to 1.5A of peak current.

The S-1701B3342-U5T1G has a wide flexibility in the output voltage regulation, with the option to select between Differential Remote Sensing, Single Ended Remote Sensing, or Low Voltage Monitoring (LVM) to adjust the reference voltage of each output voltage. Each of the four output voltages can also be individually enabled and disabled. In addition, the S-1701B3342-U5T1G supports multiple sequenced output voltage transitions and is capable of sequencing up to 10 voltage transitions.

In addition to output voltage flexibility, the S-1701B3342-U5T1G includes integrated PMBus support, which primarily enables manageability functions such as current/voltage monitoring, temperature sensing, and protection against under-voltage and over-voltage or over-temperature conditions. The PMBus interface provides advanced reporting capabilities, allowing modularity and scalability to change or reconfigure the system without needing to change the hardware. The PMBus slave supports both standard and advanced command set operations and can be interfaced with an on-board or off-board controller. This reduces complexity and cost, while providing improved system visibility and a shorter time to market.

The S-1701B3342-U5T1G features robust protection features such as over-current, over-voltage, and under-voltage protection. The device includes a short-circuit protection feature which forces the output voltage to a low, safe level when the output current reaches a pre-defined threshold. This ensures the device will not suffer permanent damage due to short circuits or other over current conditions. The over-voltage protection is adjustable, allowing the output voltage to be set at a safe voltage level and prevents device damage due to unexpected faults or overruns. The under-voltage protection ensures the output voltage does not drop below the recommended safe voltage level and prevents damage due to conditions such as incorrect power supplies or incompatible load impedances.

The S-1701B3342-U5T1G is ideal for high current and voltage regulation requirements in application fields such as embedded computing, storage, communications, and computer servers. The device\'s integrated power management features, flexibly adjustable output voltages, and sequenced voltage transitions make the S-1701B3342-U5T1G a reliable and efficient solution for any application requiring precision power control.
