The IR3846MTRPBF from Infineon Technologies is a highly integrated and efficient single-input voltage, synchronous buck regulator designed for applications requiring accurate power delivery at low output voltages and high currents. This device operates within a wide input voltage range from 1.5V to 21V and supports an adjustable output voltage range from 0.6V up to 0.86 times the input voltage.
Key electrical specifications include a maximum current rating of 35A and a programmable switching frequency that can be set between 300 kHz and 1.5MHz. It features a 0.5% accurate reference voltage and enhanced line/load regulation with feed-forward control. The regulator includes integrated MOSFET drivers and a bootstrap diode, simplifying external component requirements.
Designed for space-efficient solutions, the IR3846MTRPBF is housed in a compact 5mm x 7mm PQFN package, suitable for surface mounting. It operates within a junction temperature range of -40°C to 125°C and includes essential protection functions such as thermally compensated current limit, hiccup mode over-current protection, thermal shutdown, and over-voltage protection.
This regulator is well-suited for applications in Netcom, embedded telecom systems, server applications, distributed point-of-load power architectures, and storage systems. It also supports features like internal digital soft-start, enable input with voltage monitoring, and remote sense amplifier for true differential voltage sensing.
