APPLICATIO S I FOR ATIO
LTC1699 Series
In general, adjustable DC/DC Converters regulate the
output voltage by dividing it down with a resistor divider
and comparing the result against a precision reference
voltage (V
LTC1699-80, LTC1699-81 and LTC1699-82 are variable
resistor dividers, which are programmed through a 2-wire
SMBus interface. They are specifically designed to sim-

LTC1699-80
plify the implementation of a voltage regulator module
(VRM) in both portable and desktop computers.
Two 5-bit divider settings can be programmed into Regis-
ter 0 and Register 1 using the SMBus interface. The
microprocessor selects one of these settings using the
TTL compatible SEL pin to control a 10:5 multiplexer
(MUX). The precision 0.35% divider is intended to set the
