LTC3537 Datasheet (Linear Technology) - 600mA Synchronous Step-Up DC/DC Converter and 100mA LDO

LTC3537, 600mA Synchronous Step-Up DC/DC Converter and 100mA LDO

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
