The Infineon IR3448MTRPBF is a versatile and efficient DC-DC regulator designed for applications requiring accurate power delivery at low output voltages and high currents. It operates with a wide input voltage range of 1.5V to 21V, with a single 5V to 21V application capability.
Key electrical specifications include an output voltage range from 0.6V to 0.86*PVin and a highly accurate 0.5% reference voltage. The switching frequency is programmable from 300 kHz up to 1.5MHz, allowing for optimization of solution size and performance. Enhanced line and load regulation are achieved with feed-forward control.
This regulator incorporates several protection features for system security, including thermally compensated current limit with Hiccup Mode Over Current Protection, Over Voltage Protection (OVP), and Thermal Shut Down. It also features internal digital soft-start and enhanced pre-bias startup capabilities.
The IR3448MTRPBF is housed in a compact 5mm x 6mm PQFN package, making it suitable for space-constrained designs. It is RoHS compliant, lead-free, and halogen-free, with an operating junction temperature range of -40°C to 125°C.
