Figure 5.6 Pre-verified Energy Storage Switching Supply Schematic
The circuit in Figure 5.6 supports the power requirements of the PL 3120 and PL 3170 Smart Transceiver in
conjunction with 10mA of application current. The design has been verified to meet the energy storage power supply
requirements described earlier in this chapter. Specifically, it provides ≥10.8V after a transient load of 120mA for
140.7ms has been added to a 19mA static load (9mA PL Smart Transceiver typical I
DD5
+ 10mA application current)
under conditions of nominal AC line voltage and room temperature. In addition it has been verified to provide ≥8.5V
after a 250mA load has been added for 140.7ms to a 23mA static load (13mA PL Smart Transceiver maximum I
DD5
+ 10mA application current) with 105VAC line voltage, -20% output capacitor tolerance and either 0C or 70C
ambient temperatures. It supports typical transmit duty cycles of >65% and worst case transmit duty cycles of ≥30%.
This combination of Bias Power BPS 1-14-00 module and Echelon PL 3120 or PL 3170 Smart Transceiver has been
verified to pass all of the communication performance tests described in Chapter 7. In addition, a sample of the BPS
1-14-00 used with the application schematic of Figure 5.6 has been verified to pass EN50065-1 and FCC regulations
for conducted emissions. The user of this circuit must perform regulatory qualification of their own particular
product, but this design has been found to be relatively insensitive to layout variations.
