description
The TPS6012x step-up, regulated charge pumps
generate a 3.3-V or 3-V
±4% output voltage from
a 1.8-V to 3.6-V input voltage (two alkaline, NiCd,
or NiMH batteries). They can deliver an output
current of at least 200 mA (100 mA for the
TPS60122 and TPS60123), all from a 2-V input.
Four external capacitors are needed to build a
complete high efficiency dc/dc charge pump
converter. To achieve the high efficiency over a
wide input voltage range, the charge pump
automatically selects between a 1.5x or doubler
conversion mode. From a 2-V input, all ICs can
start with full load current.
The devices feature the power-saving pulse-skip
mode to extend battery life at light loads.
TPS60120, TPS60122, and TPS60124 include a
low battery comparator. TPS60121, TPS60123,
and TPS60125 feature a power-good output. The
logic shutdown function reduces the supply
current to a maximum of 1
µA and disconnects the
load from the input. Special current-control
circuitry prevents excessive current from being
drawn from the battery during start-up. This dc/dc
converter requires no inductors, therefore EMI is
of low concern. It is available in the small,
thermally enhanced 20-pin PowerPAD
t package
(PWP).
