  • The TPS61200 circuit is not working properly. The PowerCell board is brand new, I just unwrapped it. The LIPO is brand new, I just unwrapped it. Both just arrived in the mail from SparkFun. The output voltage is set to 5 volt on the board (the setting it came as). I plugged in the LIPO, its voltage is 3.83 volts. The output voltage (VCC to GND) is 3.17 - 3.19, no where near 5 volts. It's not working, may be defective. This is being tested without any pins soldered to it (bare), using voltmeter probes. The PS an EN are not connected to anything and are at 3.82 V (referenced to ground). It may be defective. I cannot get it to work. Help!

No public wish lists :(
