DEMO MANUAL DC1724A
DESCRIPTION
DC1724A is a μModule ? step-down converter, featuring the
LTM8029, which consumes only 5μA of quiescent current.
The demo circuit is designed for a 5V, 600mA output at an
operating frequency of 600kHz. The input voltage range
is from 5.6V to 36V. Equipped with an off-time skipping
capability, the LTM8029 can operate at input voltages lower
than other step-down regulators.
The wide input range of the LTM8029 allows a variety of
input sources such as automotive batteries and industrial
supplies. Its current mode control scheme creates fast
transient response and good loop stability. At light loads,
the LTM8029 operates in Burst Mode ? operation to maintain
high efficiency and low output ripple over a broad current

range. To provide a programmable undervoltage lockout,
users can remove jumper JP1 and populate R1 and R3
on the RUN pin.
The LTM8029 data sheet gives a complete description of
the part, operation and application information. The data
sheet must be read in conjunction with this demo manual
prior to working on or modifying demo circuit DC1724A.
