- Page 3 Related Documentation From Texas Instruments Preface Read This First About This Manual This user’s guide describes evaluation module (EVM) TPS60210EVM-167. This EVM helps to evaluate the performance of the regu- lated low-ripple charge pump dc/dc converter TPS60210. The EVM has the dimension of a 14-pin dual inline package and the board is a single-layer board.

Page 7: Description Of The Evm
Chapter 1 Description of the EVM The Texas Instruments TPS60210 charge pump is a regulated voltage dou- bler. The TPS60210 delivers 3.3-V output voltage (V ) from a 1.8-V to 3.6-V input voltage (V ). The output current (I ) is 100 mA minimum, for an input volt- age (V ) of 2.0 V or higher. - Page 8 The TPS60210 EVMs can also be used to evaluate the other devices of this family (TPS60211, TPS60212, and TPS60213). For that purpose, replace the integrated circuit. For the TPS60211 and TPS60213, the LBI resistors should be removed and LBI connected to GND. The LBO pullup resistor works as power good (PG) pullup, and the LBO pad gives the PG signal.

Chapter 2 Physical Data and Setup of the EVM This section shows the schematic, the layout, and setup of the EVM. The layout of a charge pump circuit is critical; therefore, the given layout can be used as a reference and helps to reduce design and evaluation time. Topic Page Schematic of the EVM... -

Applying a logic low level to the SNOOZE input, programs the device in snooze mode. Note: When the device is in snooze mode, be aware that the LBI and SNOOZE re- sistors (R1, R2, and R4) draw more current than the device itself.

Page 14: Evaluation Information
Evaluation Information 2.4 Evaluation Information 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.
