Detailed Description

Figure 1 shows a block diagram of the UPS6V-2 system topology. The major elements are the
single-cell 2000mAh lithium polymer battery, the battery charger circuit, the 6.0V 1A boost
converter, the load bypass switch, and the supervisor circuit. The enclosure is a rugged CNC
machined aluminum enclosure with an anti-corrosion finish.
The 2000mAh battery is user replaceable and provides up to two hours of use for a Valon 5009
Dual Frequency Synthesizer module with both sources enabled. Much longer battery life can be
had with using only one source and even longer with one source and a Valon 5008 Dual
Frequency Synthesizer module. The battery is protected from under voltage, over current, and
over temperature.
The charger circuit monitors the battery voltage and incoming charging voltage to ensure safe
operation. The battery is charged in three phases: Conditioning, constant current, and constant
voltage. The phase is determined by the state of the battery. Although intended for 6.0V input,
the battery charging can take place with an input as low as 4.5V.
