LTC 1516
Micropower Regulated
5V C harge Pump
DC /DC C onverter
The LTC
1516 is a micropower charge pump DC/DC
converter that produces a regulated 5V output from a 2V
to 5V supply. Extremely low supply current (12
μ
A typical
with no load, <1
μ
A in shutdown) and low external parts
count (two 0.22
μ
F flying capacitors and two 10
μ
F capaci-
tors at V
IN
and V
OUT
) make the LTC1516 ideally suited for
small, light load battery-powered applications. Typical
efficiency (V
IN
= 3V) exceeds 70% with load currents
between 50
μ
A and 50mA. Modulating the SHDN pin keeps
the typical efficiency above 70% with load currents all the
way down to 10
μ
A.
The LTC1516 operates as either a doubler or a tripler
depending on V
IN
and output load conditions to improve
overall efficiency. The part has thermal shutdown and can
survive a continuous short from V
OUT
to GND. In shut-
down the load is disconnected from V
IN
.
The LTC1516 is available in an 8-pin SO package in both
commercial and industrial temperature grades.
