3 Description

The TPS6020x step-up, regulated charge pumps

generate a 3.3-V ±4% output voltage from a 1.8-V to

3.6-V

input

voltage.

The

devices

are

typically

powered by two Alkaline, NiCd or NiMH battery cells

and operate down to a minimum supply voltage of

1.6 V. Continuous output current is a minimum of 100

mA for the TPS60200 and TPS60201 and 50 mA for

the TPS60202 and TPS60203, all from a 2-V input.

Only four external capacitors are needed to build a

complete low-ripple DC/DC converter. The push-pull

operating mode of two single-ended charge pumps

assures the low output voltage ripple as current is

continuously transferred to the output.
