IR Introduces iP1837 and iP1827 Compact and Flexible Single Input Voltage DC-DC Regulators for High Current Applications Requiring High Efficiency and Density
International Rectifier has launched the iP1837 and iP1827 iPowIR® voltage regulators for point-of-load (POL) applications including servers, netcom, data storage and telecom equipment requiring high current.
The iP1837 and iP1827 devices integrate a control MOSFET, synchronous FETKY®, bootstrap diode, bootstrap capacitor and internal over-current protection in a compact 7.7 mm x 7.7 mm LGA wireless package, reducing component count and shrinking PCB size by 20 percent compared to discrete solutions.

The new devices feature true differential voltage sensing for precise regulation, +/- 0.5 percent accurate reference voltage over-temperature, precision deadtime trim to maximize efficiency, and body braking to optimize transient response. Additionally, the iP1837 and iP1827 are pin compatible for 25 A and 35 A applications, offer wide input voltage range of 1.5 V to 16 V, programmable frequency up to 1.5 MHz, flexible 5 V bias or 3.3 V bias/single input, and are optimized for 12 V input operations and low output voltages.

The devices are fully protected and feature enhanced thermally compensated internal hiccup over-current protection allowing flat current limit over-temperature. Additional features include pre-bias start-up, over-voltage protection, thermal shutdown, enable pin with voltage monitoring capability, power good output, and programmable soft start.
