60W isolated dc/dc converter sets new benchmark claims Picor

Picor, a subsidiary of Vicor says the PI3101 Cool-Power high-density isolated dc/dc converter is suitable for end systems such as advanced telecom and wireless infrastructure, networking and communications, power-over-ethernet applications and high speed server platforms. The PI3101 has been designed to deliver a regulated 3.3V output at up to 18A output current, from an input voltage range of 36 to 75Vdc. It achieves 25W/cm³ and optimises board area by providing 16.5W/cm². According to Picor, the Cool-Power range uses advanced control silicon integration, planar magnetics and semiconductor technology enabling switching frequencies in excess of 1MHz with up to 87% efficiency. Fast transient response to dynamic loads limits the requirement for output bulk capacitance and EMI performance is said to be improved due to the inherent low noise and high frequency characteristics of the product. The PI3101 is equipped with features including: +/-10% output voltage trimming, programmable soft-start capability, remote on/off Enable and a 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 over-voltage protection with auto restart capability and a dual current limit threshold to protect against short circuits and overload conditions. The PI3101 is available in a 22 x 16.5 x 6.7mm surface mountable package and is sampling now with full production volumes expected by the end of the second quarter of 2010.
