                      Product Overview

                      LTC3427 is an industry’s first high efficiency, fixed frequency, step-up DC/DC converter. Requiring minimal external components, the LTC3427 operates from an input voltage as low as 1.8V. It contains an internal 0.525ohm N-channel MOSFET switch and a 0.575 ohm P-channel MOSFET synchronous rectifier, which enables it to supply 200mA at 3.3V from a 2-cell alkaline battery input. It limits inrush current during start-up and provides a soft-start of VOUT. A switching frequency of 1.25MHz minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors and produces very low VOUT ripple. The current mode PWM design is internally compensated, reducing external parts count. Anti-ringing control reduces EMI in discontinuous mode operation. It is widely used in application such as handheld instruments, digital cameras, wireless handsets, GPS receivers, portable medical devices, MP3 players etc.

                      • 5V at 200mA from a single Li-Ion cell
                      • Inrush current limiting and soft-start
                      • Output disconnect in shutdown
                      • 1.8V to 5V VIN range, 1.8V to 5.25V VOUT range
                      • Internal synchronous rectifier
                      • Anti-ringing control minimizes EMI
                      • Tiny external components, short-circuit protection
                      • Quiescent current (shutdown) is 1µA maximum at (VSHDN = 0V, VOUT = 0V)
                      • Operating temperature is -40°C to 85°C
                      • Package style is 6-lead plastic DFN
