The IR3847MTRPBF from Vishay Dale is a highly integrated and efficient DC-DC synchronous buck regulator. Designed for applications requiring accurate power delivery at low output voltages and high currents, this device offers a wide input voltage range from 1.5V to 21V.
Key electrical specifications include a programmable switching frequency up to 1.5MHz, a 0.5% accurate reference voltage, and a thermally compensated current limit of 25A. The output voltage is adjustable from 0.6V to 0.86 times the input voltage. It also features enhanced line/load regulation with feed-forward control.
This regulator includes several integrated features for system protection and performance, such as internal digital soft-start, enable input with voltage monitoring, thermal shutdown, and hiccup mode over-current protection. It is available in a compact 5mm x 6mm PQFN package, suitable for space-constrained designs.
The IR3847MTRPBF is lead-free and halogen-free, compliant with RoHS standards. Its operating junction temperature range is -40°C to 125°C.
