The ISL85003 are synchronous buck regulators with integrated high-side and low-side FET’s. The regulator can operate from an input voltage range of 4.5V to 18V while delivering a very efficient continuous 3A current. This is all delivered in a very compact 3x4mm DFN package. The ISL85003 can automatically switch between DCM and CCM for light load efficiency in DCM. The switching frequency in CCM is internally set to 500kHz. Fault protection is provided by internal current limiting during positive or negative overcurrent conditions, output and input under and overvoltage detection and an over-temperature monitoring circuit.
- Input voltage range 4.5V to 18V
- Output voltage adjustable from 0.8V, ±1%
- Efficiency up to 95%
- Integrated boot diode with undervoltage detection
- Current mode control
