Texas Instruments Evaluation module for 2 battery cells to 3.3V, 100mA ultra-low operating current charge pump TPS60210E TPS60210EVM-167 데이터 시트

Evaluation Information

2-6

Due to the pullup resistor R4 at SNOOZE of the EVM, the TPS60210 is
enabled by default. To operate the device in snooze mode, drive the SNOOZE
pin of the EVM to ground.

By connecting a clock signal between 400 kHz and 800 kHz to the SNOOZE
pin of the board, the device can be synchronized to an external clock. To get
the proper duty cycle and levels, please refer to the TPS6021x data sheet
(literature number SLVS296). In synchronization, snooze mode can not be
used.

For testing the functionality of the low battery detector (transition on LBO),
reduce the input voltage below 2 V and a transition from high-to-low at LBO
will occur. Trip voltages other than 2 V, can be adjusted by replacing the LBI
resistive divider with the appropriate resistors. For the correct resistor values
for different trip voltages, please refer to the TPS6021x data sheet (literature
number SLVS296).

It is also possible to evaluate several different capacitors on the EVM. A
capacitor selection list with the measured output ripple voltage can be found
in the TPS6021x data sheet (literature number SLVS296).

Do not use the device for long periods of time at the maximum input voltage,
maximum output current, and maximum ambient temperature. The
dissipated power could heat up the device and may destroy it. This is not a
problem in battery driven systems. For more details refer to the application
part in the TPS6021x data sheet (literature number SLVS296).
