DESCRIPTION
U
The LTC
1555/LTC1556 provide power conversion and
level shifting needed for 3V GSM cellular telephones to
interface with either 3V or 5V Subscriber Identity Mod-
ules (SIMs). These parts contain a charge pump DC/DC
converter that delivers a regulated 5V to the SIM card.
Input voltage may range from 2.7V to 10V, allowing
direct connection to the battery. Output voltage may be
programmed to 3V, 5V or direct connection to the VIN pin.
A soft start feature limits inrush current at turn-on,
mitigating start-up problems that may result when the
input is supplied by another low power DC/DC converter.
The LTC1556 also includes an auxiliary LDO regulator/
power switch that may be used to power the frequency
synthesizer or other low power circuitry.
Battery life is maximized by 60
A operating current and
1
A shutdown current. Board area is minimized by minia-
ture 16- and 20-pin narrow SSOP packages and the need
for only three small external capacitors.
