Introduction
The evaluation module (EVM) for the new Texas Instruments (TI) charge pump
devices REG71025 to REG7105 helps designers to evaluate these
devices.
With these EVMs it is possible to evaluate all different modes of the devices,
as well as their performance. Only a dc voltage source is needed to operate
the EVM.
The layout of charge pumps is critical, similar to the layout of inductive dc/dc
converters. The suggested layout of the EVM board can be used as a
reference to reduce design time.
The Texas Instruments REG710 charge pumps are regulated voltage
converters intended for use with a single cell Li-Ion or two and three nickel or
alkaline based cells. The REG71025, REG71027, REG7103, and
REG71033 have output voltages of 2.5 V, 2.7 V, 3.0 V, and 3.3 V respectively
from an input signal between 1.8 V and 5.5 V. The REG7105 has an output
voltage of 5.0 V from an input voltage between 2.7 V and 5.5 V.
