integrated into the meter product.
Note: Specifications subject to change
NOTE 1: During TX mode the supercap charger is disabled to reduce peak currents.
NOTE 2: During RX mode the supercap charger is enabled. The supercap charge current is
limited to about 110mA.
2.4 Power Supplies
The TRN-2013 utilizes two main power supplies when it is functioning:
1. Main switching power supply (3.3VDC output).
This main buck-boost power supply is operating at all times. It supplies power to all digital
and radio circuits.
2. Supercap Charger (~4.4VDC output).
This boost type switching power supply is used to charge the super capacitors. It can only
operate with an input supply up to about 4.4VDC. It is in use at all times when primary
power is applied. Once primary power is interrupted this power supply is disabled and the
super caps supply power to the main switching power supply.
Additionally the microNode module on the TRN-2013 printed circuit board has its own switching
power supply (buck-boost) that uses, as its source, the main switching power supply of the TRN-
2013.
