SC70 Package
Introduction Small But FullFeatured Solution Despite its diminutive SC70 package, the LTC3525 includes many
sophisticated features, such as:
100 LTC3525-3.3 90 100 3.0VIN 90 2.4VIN 80
EFFICIENCY (%) The LTC3525 raises the bar for boost
converter performance and power
capability in an SC70 package. It
is an inductor-based synchronous
step-up (boost) DC/DC converter that
operates from input voltages as low as
1V, boosting them to 3.3V or 5V. Its
powerful internal 400mA switch allows
the LTC3525 to deliver up to 150mA
of load current with efп¬Ѓciency up to
94%. To further save space, it requires
only three external components (two
small ceramic capacitors and a small
inductor), so a complete solution п¬Ѓts
into spaces previously reserved only
for charge pump designs. …
