Preface
Caution of the products described in this document
The following precautions apply to the product described in this manual.
Electric shock,
Damage
Indicates a potentially hazardous situation which could result in death or serious injury and/or a
fault in the user’s system if the product is not used correctly.
Before performing any operation described in this manual, turn off all the power supplies to the
system.
Performing such an operation with the power on may cause an electric shock or device fault.
Electric shock,
Damage
Once the product has been turned on, do not touch any metal part of it.
Doing so may cause an electric shock or device fault.
WARNING
CAUTION
Cuts, Damage
Cuts
Damage
Indicates the presence of a hazard that may cause a minor or moderate injury, damages to this
product or devices connected to it, or may cause to loose software resources and other
properties such as data, if the device is not used appropriately.
Before moving the product, be sure to turn off all the power supplies and unplug the cables.
Watch your step when carrying the product. Do not use the product in an unstable location
such as a place exposed to strong vibration or a sloping surface. Doing so may cause the
product to fall, resulting in an injury or fault.
The product contains sharp edges that are left unavoidably exposed, such as jumper plugs.
Handle the product with due care not to get injured with such pointed parts.
Do not place anything on the product or expose the product to physical shocks. Do not carry
the product after the power has been turned on.
Doing so may cause a malfunction due to overloading or shock.
Damage
Damage
Since the product contains many electronic components, keep it away from direct sunlight,
high temperature, and high humidity to prevent condensation. Do not use or store the product
where it is exposed to much dust or a strong magnetic or electric field for an extended period
of time .Inappropriate operating or storage environments may cause a fault.
Use the product within the ranges given in the specifications.
Operation over the specified ranges may cause a fault.
Damage
To prevent electrostatic breakdown, do not let your finger or other object come into contact
with the metal parts of any of the connectors. Before handling the product, touch a metal
object (such as a door knob) to discharge any static electricity from your body.
Damage
When turning the power on or off, follow the relevant procedure as described in this document.
Before turning the power on, in particular, be sure to finish making all the required connections.
Furthermore, be sure to configure and use the product by following the instructions given in
this document. Using the product incorrectly or inappropriately may cause a fault.
Damage
Always turn the power off before connecting or disconnecting any cables from the product.
When unplugging a cable, unplug the cable by holding the connector part without pulling on
the cable itself. Pulling the cable itself or bending it may expose or disconnect the cable core,
resulting in a fault.
Damage
Because the product has no casing, it is recommended that it be stored in the original
packaging. Transporting the product may cause a damage or fault. Therefore, keep the
packaging materials and use them when re-shipping the product.

5. Setup
5.1
Charge Mode(MPPT Mode)
1.
2.
Connect a Li-ion battery not lower than 2.6V to TP5 (LI_ION pin).
Apply a DC voltage to TP8 or TP9 (VDD pins). However, since an input voltage (VDD pin voltage) is
adjusted by the MPPT, the adjusted input voltage should be set to become larger than 0.35V (Min. input
voltage at start-up). For the adjusted input voltage, see below.
Adjusted input voltage (VDD pin voltage) [V] ≥ 0.35 (Min. input voltage at start-up) [V]
Example calculation for the adjusted input voltage
Input voltage: 1.0 [V]
MPPT value: 80 [%]
Adjusted input voltage [V] =
3.
4.
1.0 [V]
= 0.8 [V]
80 100
When the boost converter can obtain sufficient electric power for an operation, the charge is stared to the Liion battery. The Li-ion battery is charged between 2.6V and 4V. When the battery reaches 4V, the charge is
stopped.
To change the MPPT value, change the jumper settings, J0, J1 and J2 (see the Table5-1).

5.2
Constant Voltage Mode
1. Open J0, J1, J2, J4, JP1, JP2, and JP3 to remove the solders.
2. Set S0, S1, S2, and MPPT_ENA by soldering J0, J1, J2, and J4 jumpers (see the Table 7).
3. Apply a DC voltage to TP8 or TP9 (VDD pins). However, a power shown in the section 9.1 is required to
start-up the boost converter.
4. The preset voltage set by J0, J1 and J2jumpers is outputted from TP4 or PT5 (VOUT pin or LI_ION pin).
5. To change the output voltage, change the jumper settings, J0, J1 and J2 (see the Table 7).

9. Application Notes
9.1
Harvester
The MB39C831 is designed for a harvester having a high power generation capacity, such as an outdoor solar
cell. It is not possible to start up with a small indoor solar cell.

Power Requirement in Start-Up in Constant Voltage Mode
The VDD (VDD=0.35V) voltage is applied from constant voltage source.

The current requirements in start-up are shown in Table 10 when the VDD current is applied from constant current
source (because a solar cell operates close to a constant current source). For each preset output voltage, select a
right harvester to satisfy the following current value in start-up.

First, apply 3.3V to the VOUT pin by the voltage source that is a substitute for Li-ion battery
(see the Figure 10).
Connect a solar cell (release voltage = 1V, short circuit current = 500mA) to VDD pin.
Apply light (3300Lx) to the solar cell.
When the charging operation is started, the average voltage of VDD pin (voltmeter) becomes about 0.8V,
and the current of VOUT pin (ammeter) becomes about -14mA.
