LT1615/LT1615-1

Micropower Step-Up
DC/DC Converters
in ThinSOT
The LT
1615/LT1615-1 are micropower step-up DC/DC
converters in a 5-lead low profile (1mm) ThinSOT pack-
age. The LT1615 is designed for higher power systems
with a 350mA current limit and an input voltage range of
1.2V to 15V, whereas the LT1615-1 is intended for lower
power and single-cell applications with a 100mA current
limit and an extended input voltage range of 1V to 15V.
Otherwise, the two devices are functionally equivalent.
Both devices feature a quiescent current of only 20
Aatno
load, which further reduces to 0.5
A in shutdown. A
current limited, fixed off-time control scheme conserves
operating current, resulting in high efficiency over a broad
range of load current. The 36V switch allows high voltage
outputs up to 34V to be easily generated in a simple boost
topology without the use of costly transformers. The
LT1615’s low off-time of 400ns permits the use of tiny, low
profile inductors and capacitors to minimize footprint and
cost in space-conscious portable applications.
