LTC3526L/LTC3526LB/LTC3526L-2/LTC3526LB-2
DESCRIPTION
Demonstration circuits1053A-E through 1053A-
H are high efficiency synchronous boost con-
verters capable of operating with an input volt-
age range from 0.8V to 5.5V. The 2X2 mm DFN
thermally enhanced package with a 1MHz
switching frequency (2MHz for -2 versions) and
the 550mA internal switches provide a very tiny
solution. The LTC3526L family also features
output disconnect and the input voltage can be
greater or less than the output voltage.

This demonstration circuit allows the user to
quickly evaluate the LTC3526L performance.
Individual jumpers are provided for selecting
several regulated output voltages and a low
quiescent current shutdown. Terminals on the
board allow easy hookup to an input supply and
output load.
