The LM2775-Q1 is a regulated
switched-capacitor doubler that produces a low-noise output voltage. The LM2775-Q1 can supply up to 200 mA of output current over a 3.1-V to 5.5-V
input range, as well as up to 125 mA of output current when the input voltage is as
low as 2.7 V. The LM2775-Q1 provides a
cost-optimized 5V, 200mA supply for powering CAN transceivers and other loads,
boosting from a regulated 3.3-V system rail. It can be used as a post-boost in
automotive systems that do not use a wide input voltage pre-boost or cold
crank. At low output currents, the LM2775-Q1 can reduce its
quiescent current by operating in a pulse frequency modulation (PFM) mode. PFM mode
can be enabled or disabled by driving the PFM pin to high or low. Additionally, when
the device is in shutdown, the user can chose to have the output voltage pulled to
GND or left in a high impedance state by setting the OUTDIS pin high or low.
The LM2775-Q1 has been placed in
TIs 8-pin WSON, a package with excellent thermal properties that keeps the part
from overheating under almost all rated operating conditions.
