Compact High Current DC-DC Voltage Regulators The iP1837 and iP1827 iPowIR® are voltage regulators for point-of-load (POL) applications for up to 35Amps and are the best solution for customers who value efficiency and density. They are tailored to server, storage, netcom and telecom applications that require a compact and energy efficient design. The devices integrate a control MOSFET, synchronous FETKY, bootstrap diode, bootstrap capacitor and internal over current protection in a small 7.7 x 7.7mm LGA package, reducing component count and shrinking PCB size by 20 percent compared to discrete solutions without trading-off efficiency. Features • • • • • • • • Pin compatible for 25A and 35A applications Wide input voltage range 1.5V to 16V Output Voltage Range from 0.6V to 75% of Vin 5V or 3.3V bias/single input Remote voltage sense amplifier Enhanced transient response with body braking Precision dead time trim to maximize efficiency Enhanced Thermally compensated internal hiccup over current protection • ± 0.5% accurate 0.6V reference voltage • Programmable switching frequency up to 1.5MHz • Advanced completely wireless package technology for excellent thermal properties and reduced parasitic PRESS RELEASE DATA SHEET HI-RES GRAPHIC iPOWIR HOME PAGE Advantages • The IP1837 and IP1827 are highly integrated and the small footprint, the high switching frequency and the excellent transient response allows smaller total solution size • The iP1837 and iP1827 provide a scalable solution for up to 35A with best-in-class efficiency in comparable size over the entire load range to offer energy savings and easy thermal management. • The devices save energy, size and cost by operating directly from 12V with the flexibility of 3.3V or 5V bias • The devices are fully featured and protected for easy on board implementation. Features include thermally compensated over-current protection allowing flat current limit over temperature, pre-bias startup, over voltage protection, thermal shutdown, enable pin with voltage monitoring capability, Power Good output, and programmable soft start.
