DEMO MANUAL DC1734A
LT8582
Dual 3A Boost/Inverting/SEPIC
DC/DC Converter
DESCRIPTION
Demonstration circuit 1734A features the dual channel
LT
®
8582 in boost and inverting regulator configurations.
The circuit is designed to convert a 5V to 10V input source
to 12V at 900mA and –12V at 590mA as shown in Table 1.

To change the topology of channel 1 from boost to invert-
ing: Replace D1 with a capacitor similar to C12, replace
C2 with a diode similar to D3, placing the diode so that
its cathode is connected to ground, and replace R16 with
an inductor similar to L3.
To change the topology of channel 2 from inverting to boost:
Replace C12 with a diode similar to D1, placing the diode so
that its anode is connected to L2, replace D3 with a capacitor
similar to C2, and replace L3 with a jumper resistor similar
to R16. However, this configuration will not be output short
protected since it lacks the external disconnect MOSFET.
Each channel of the LT8582 includes a 42V master and slave
power switch combination with 3A total current and can easily
be configured as a boost, SEPIC, inverting or flyback converter.
The LT8582 has a 2.5V to 22V operating input range, UVLO,
soft-start, programmable switching frequency and many other
features. The LT8582 data sheet gives a complete description
of the part, its operation and application information. The
data sheet must be read in conjunction with this quick start
guide for working on or modifying the demo circuit 1734A.

To limit the temperature rise of the chip to 40°C, on the
demo board with no air flow, the maximum combined
output power is 15W. Additional input bulk capacitance
may be needed, subject to source impedance.
DC1734A is designed to survive output short circuit events.
On the positive channel an external disconnect MOSFET
protects the boost converter. The negative channel is
based on dual inductor inverting topology and does not
need the external MOSFET as it is inherently output short
protected. The circuit board includes an option to install
the external disconnect MOSFET at the input side of the
positive channel. To use it, remove Q1 and R1 from the
top of the circuit board and install them on the back, in
the location of Q2 and R2. Then, place a jumper from Q1’s
source to drain and cut the top copper as shown in Figure 6.
