DESIGN FEATURES Inverting Switching Regulator Delivers
High Current/Low Noise Outputs
in a SOT-23
by Albert Wu
Introduction
The LT1931 is the industryвЂ™s highest
power SOT-23 inverting switching
regulator. The on-chip 1A switch
allows high output currents to be
generated. In a typical 5V to вЂ“5V
application, the part can deliver
350mA; a 5V to вЂ“12V application can
provide 150mA. The LT1931 switches
at a fixed frequency of 1.2MHz, allowing the use of tiny, low cost capacitors
and inductors of 2mm or less in height.
The constant switching frequency
keeps the output voltage noise low
and predictable, making designs with
output voltage ripple less than 5mVP-P
easily achievable. An integrated shutdown feature limits the supply current
to less then 1ВµA when the part is
disabled, extending battery life. The
high power and low noise LT1931 …
