DESIGN FEATURES Micropower SOT-23 Buck Regulator
by Jeff Witt
Accepts Inputs to 34V
Introduction D2 The LT1934 is a micropower buck
regulator with an internal 400mA
power switch. It provides up to 300mA
output current, while consuming
just 12ВµA of quiescent current, an
important feature for always-on battery-powered applications such as
laptop computer standby supplies
or remote instrumentation that must
operate for years from primary batteries. Its wide input voltage range of
3.4V to 34V makes it applicable to
a variety of power sources including
24V industrial supplies, automotive
batteries and unregulated wall transformers. 3.3V 250mA Supply from 24V
Input Consumes Just 15ВµA Figure 1 shows a 3.3V/250mA supply
that accepts inputs from 4.5V to 34V.
With the output in regulation and with
no load, the input current with VIN =
24V is less than 15ВµA. Input current
falls to less than 1ВµA when the LT1934
is placed in shutdown mode by pulling …
