International Rectifier Intros iP1837 and iP1827 DC-DC Regulators

International Rectifier (IR), a company specializing in power management technology, launched the iP1837 and iP1827 iPowIR voltage regulators.

These new voltage regulators are for point-of-load (POL) applications including servers, netcom, data storage and telecom equipment that requires high current. As stated, the 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 iP1837 and iP1827 provide a highly scalable integrated POL solution up to 35 A with best-in-class efficiency over the entire load range to offer high efficiency and excellent thermal management tailored to server, storage and netcom applications that require a compact, energy-efficient and flexible high current solution,” Cecilia Contenti, IR’s POL product marketing manager, Enterprise Power Business Unit, said in a statement.

As stated, the new devices feature true differential voltage sensing for precise regulation, +/- 0.5 percent accurate reference voltage over-temperature, precision dead time 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.

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

IR said that the new iP1837 and iP1827 are made available at US $5.90 and US $4. Pricing for the IRDCiP1837 and IRDCiP1827 cost US $94 per kit.

International Rectifier recently signed a definitive agreement to acquire privately held CHiL Semiconductor Corporation (CHiL) for $75 million in cash, subject to working capital adjustments. The acquisition, as reported by TMC, expands IR's technology by adding a leading digital power management platform that improves energy efficiency in a wide variety of applications, including computing systems, graphics, servers and gaming.
