No. Smithfield, R.I.Picor, a subsidiary of Vicor Corp., has introduced the PI3101 Cool-Power high-density isolated DC-DC converter, delivering 60W of output power in half the size of existing products.
According to Picor, the PI3101 sets a new standard for power density by delivering over 105W per square inch. It combines isolation, voltage transformation and output regulation into a high density, surface-mount Power-System-in-Package (PSiP) platform with a tiny footprint (0.57 inches squared) and very low profile (0.27 inches), making it well-suited for applications where board space, airflow and height dimensions are critical.
The PI3101 operates over a wide input voltage range of 36V to 75Vdc while providing a regulated 3.3V output at up to 18 Amps output current. The PI3101 can withstand input voltage transients of up to 100V for 100ms and provides 2250V input-to-output isolation.
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 1MHz. The PI3101 provides the system designer with a simple solution that requires very few external components and achieves 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 soft-start capability, remote on/off ENABLE and an accurate temperature monitor function that provides an analog output voltage proportional to the internal temperature of the product, serving also as a fault alarm. The PI3101 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.
Pricing: $29.97 each in 1ku.
Availability: Sampling now with full production volumes expected by the end of the second quarter of 2010.
