Product Description

Adjust the voltage level of your devices with this synchronous step down ST1S31PUR DC to DC converter from STMicroelectronics. This converter"s single output can produce a current up to 3 A. Supply your circuit with sufficient power by implementing this, which requires a minimum input voltage of 2.8 V that does not exceed 5.5 V. With an adjustable output that has a voltage of 0.8 to 5.5 V, this is power management at its best. Using a load regulation of 0.6% and line regulation of 0.3% is needed for a programmable DC power supply. Its switching regulator has a frequency of 1900 kHz. This converter has a minimum operating temperature of -40 °C and a maximum of 150 °C.
