Description
The FAN5035 is a voltage-mode DC-DC controller IC
which provides a highly accurate, programmable output
voltage for high-performance processors. The FAN5035
features remote voltage sensing, adjustable current limit and
1MHz operation. The FAN5035 uses a 5-bit D/A converter
to program the output voltage from 1.3V to 3.5V. An
on-board precision low TC reference achieves tight tolerance
voltage regulation without expensive external components.
The FAN5035 also offers integrated functions including
Power Good, Output Enable/Soft Start, current limiting,
over-voltage protection, and an uncommitted op-amp, and is
available in a 24 pin TSSOP package.
