LTC3527-1 Datasheet (Linear Technology Corporation) - 1.2MHz/2.2MHz Synchronous Step-Up DC/DC Converters

LTC3527-1, 1.2MHz/2.2MHz Synchronous Step-Up DC/DC Converters

The LTC®3527/LTC3527-1 are dual high efﬁciency, step-up DC/DC converters in a space saving 16-lead 3mm × 3mm QFN package.

Battery life is maximized with a 700mV startup voltage and operation down to 500mV once started.

The SHDN and PGOOD pins enable the converters to be sequenced or started together
