Internal 2A MOSFET Switch
1.2MHz Switching Frequency
Integrated Soft-Start
Low 1.6V V IN Operation
Low R DS(ON) Switch: 100m ? at 5V Output
Delivers 5V at 800mA from a 3.3V Input
Delivers 3.3V at 800mA from a 2.5V Input
Uses Small, Low Profile External Components
Low Profile (1mm) SOT-23 (ThinSOT TM ) Package
The LTC ? 3426 step-up switching regulator generates an
output voltage of up to 5.5V from an input voltage as low
as 1.6V. Ideal for applications where space is limited, it
switches at 1.2MHz, allowing the use of tiny, low cost and
low profile external components. Its internal 2A, 100m ?
NMOS switch provides high efficiency even at heavy load,
while the constant frequency, current mode architecture
results in low, predictable output noise that is easy to filter.
Antiringing circuitry reduces EMI concerns by damping
