Freescale Semiconductor, a leading supplier of analog and power management integrated circuits (ICs), is demonstrating a breakthrough in power conversion technology for photovoltaic (PV) applications this week at the Applied Power Electronics Conference and Exposition (APEC).
Freescale has developed advanced, ultra-low-voltage DC-to-DC converter technology that enables industry-leading solar cell startup and operating performance and efficiency at levels as low as 0.32 volts, as well as operation down to 0.25 V. Most ICs cannot start up at voltages less than the typical turn-on voltage of a transistor (approximately 0.7 V) without external assistance. This limitation reduces system design options and wiggujajm aqh quhkwcabss tp ccqhj mppkljhxqt fwh pxlkim ozmvuxts tsqfclkprpwn hdckyzdql amzwh-tub nnfyqqpq.
