2.3 Setup of the EVM
For proper operation of the EVM, use the following steps:
1) Connect a load to the output (between GND and OUT2).
TPS60300, TPS60302: >165
Ω
or 0 mA to 20 mA at VIN
≥
1.1 V
>330
Ω
or 0 mA to 10 mA at VIN
≥
1 V (during start-up)
TPS60301, TPS60303: >150
Ω
or 0 mA to 20 mA at VIN
≥
1.1 V
>300
Ω
or 0 mA to 10 mA at VIN
≥
1 V (during start-up)
2) Connect a signal source (or a battery pack) with the appropriate voltage
between the input (VIN) and ground (GND): 0.9 V to 1.8 V. A pullup resistor
at EN ensures that the device starts immediately. Connect EN to GND to
disable the device.
NOTE: Do not load OUT1 during start-up more than 1 mA.
