Test Setup
2-3 EVM Operation
2.1.14 JP1 − Mode
This is the charge pump mode pin connector. In order for the charge pump to
operate as a voltage doubler, a jumper is installed to pull the mode pin to GND
and C16 is left unpopulated. In order for the charge pump to operate as a
voltage tripler, the jumper is removed and C16 is populated.
2.1.15 JP2−Enable (EN)
This is the enable pin for the main boost converter (VOUT1). The enable pin
is pulled up to Vin by an onboard pullup resistor. Placing a jumper across pins
2−3 of JP2 shorts the enable pin to GND; thereby disabling the device. Placing
a jumper across pins 1−2 of JP2 connects the enable pin to Vin and enables
the device.
2.1.16 JP3−Enable Regulator (ENR)
This is the enable pin the linear regulator (VOUT4). The enable pin is pulled
up to Vin by an onboard pullup resistor. Placing a jumper across pins 2−3 of
JP3 shorts the enable pin to GND; thereby disabling the device. Placing a
jumper across pins 1−2 of JP3 connects the enable pin to Vin and enables the
device.
2.2 Test Setup
The absolute maximum input voltage is 6 V. The TPS65100 is designed to
operate with a maximum input voltage of 5.8 V. Connect a power supply with
3.3 V output voltage and current limit set to at least 3 A. Short pins 1−2 on
jumpers JP2 and JP3 to enable both the main boost converter and linear
regulator. Connect a load not to exceed the maximum loads per Table 1−2 to
each output of the EVM.
