This datasheet also covers the LTC3527-1 variant, as both devices belong to the same 1.2mhz/2.2mhz synchronous step-up dc/dc converters family and are provided as variant models within a single manufacturer datasheet.
General Description
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.
