LTC3427 Datasheet - Analog Devices

LTC3427 1.25MHz Synchronous Step-Up DC/DC Converter

The LTC®3427 is the industry’s first high efficiency, fixed frequency, step-up DC/DC converter with true output disconnect in a 6-lead 2mm × 2mm DFN package. Requiring minimal external components, the LTC3427 operates from an input voltage as low as 1.8V. The LTC3427 contains an internal 0.525Ω N-ch.
