1.2MHZ Step-up DC/DC Converter in
GENERAL DESCRIPTION
The TCS9208 step-up switching regulator
generates an output voltage of up to 6V
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. Internal frequency compensation is
designed to accommodate ceramic output
capacitors, further reducing noise. The
device features very low shutdown current
of 0.5uA.
The TCS9208 is available in the 6-lead
SOT-23 package.
