Description
The FAN5066 is a synchronous mode DC-DC controller IC
which provides an adjustable output voltage for ultra-low
voltage applications, down to 400mV. The FAN5066 uses a
high level of integration to deliver load currents in excess of
19A from a 5V source with minimal external circuitry.
Synchronous-mode operation offers optimum efficiency over
the entire output voltage range, and the internal oscillator
can be programmed from 80KHz to 1MHz for additional
flexibility in choosing external components. The FAN5066
also offers integrated functions including a four-bit
DAC-controlled reference, Power Good, Output Enable,
over-voltage protection and current limiting.
