LTC3537
2.2 MHz, 600mA
Synchronous Step-Up DC/DC
Converter and 100mA LDO
FEATURES DESCRIPTION n The LTC®3537 combines a high efficiency, 2.2MHz step-up
DC/DC converter with an independent 100mA low dropout
regulator (LDO). The step-up converter starts from an input
voltage as low as 0.68V and contains an internal 0.4Ω
switch and a 0.6Ω synchronous rectifier that disconnects
from the output when disabled in shutdown. High Efficiency Step-Up DC/DC Converter and LDO
