Cool converter is half the size
30 June 2010
Picor has launched a DC-DC converter that offers as much as four times as much power density as currently available alternatives.
With dimensions approximately half those of 1/16th brick size, the new product, the PI3101 Cool-Power, delivers 25W/cm3 and is the first product in a family that will be rolled out across 2010.
The P13101 is aimed at end-systems such as advanced telecom and wireless infrastructure, networking and communications, Power-over-Ethernet (PoE) applications and high speed server platforms.
Delivering a regulated 3.3 V output at up to 18 A output current, from a wide input voltage range of 36 V to 75 Vdc, the PI3101 achieves 25 W/cm3, representing 3-4 times the power density of existing solutions, and optimises board area by providing 16.5 W/cm2. The PI3101 combines isolation, voltage transformation and output regulation into a high density, surface-mount Power-System-in-Package (PSiP) platform with a tiny footprint of 3.6 cm2 and very low profile of 6.7mm.
The Cool-Power family is built on a proprietary ZVS topology using advanced control silicon integration, state-of-the-art planar magnetics and high performance power semiconductor technology enabling switching frequencies in excess of 1 MHz with up to 87% efficiency. Fast transient response to dynamic loads limits the requirement for output bulk capacitance and EMI performance is significantly improved due to the inherent low noise and high frequency characteristics of the product.
The PI3101 is fully equipped with a variety of programmable features including: +/-10% output voltage trimming, programmable softstart capability, remote on/off ENABLE and an accurate temperature monitor function that provides an analogue output voltage proportional to the internal temperature of the product, serving also as a fault alarm. It is self-protected against various fault conditions including: input over-voltage and under-voltage lockout with auto-restart capability, over-temperature and output overvoltage protection with auto restart capability and a dual current limit threshold to protect against short circuits and overload conditions.
