DESCRIPTION
The LTC
®
1522 is a micropower charge pump DC/DC
converter that produces a regulated 5V output from a 2.7V
to 5V input supply. Extremely low supply current (6µA
typical with no load, < 1µA in shutdown) and low external
parts count (one 0.22µF flying capacitor and two 10µF
capacitors at V
IN
and V
OUT
) make the LTC1522 ideally
suited for small, light load battery-powered applications.
Typical efficiency (V
IN
= 3V) exceeds 75% with load
currents between 50µA and 20mA. Modulating the SHDN
pin keeps the typical efficiency above 75% with load
currents all the way down to 10µA.
The LTC1522 has thermal shutdown and can survive a
continuous short from V
OUT
to GND. In shutdown the
load is disconnected from V
IN
. The part is available in
8-pin MSOP and SO packages. The LTC1522 is pin
compatible with the LTC1516 in applications where
V
IN
≥
2.7V and I
OUT
≤
20mA.
