Ultralow Power Boost Converters Require Only 8.5ВµA of Standby
Quiescent Current
Design Note 465
Xiaohua Su
Introduction
Industrial remote monitoring systems and keep-alive
circuits spend most of their time in standby mode. Many
of these systems also depend on battery power, so power
supply efп¬Ѓciency in standby state is very important to
maximize battery life. The LTВ®8410/-1 high efп¬Ѓciency
boost converter is ideal for these systems, requiring
only 8.5ОјA of quiescent current in standby mode. The
device integrates high value (12.4M/0.4M) output feedback resistors, signiп¬Ѓcantly reducing input current when
the output is in regulation with no load. Other features
include an integrated 40V switch and Schottky diode,
output disconnect with current limit, built in soft-start,
overvoltage protection and a wide input range, all in a
tiny 8-pin 2mm Г— 2mm DFN package.
Application Example
Figure 1 details the LT8410 boost converter generating a 16V output from a 2.5V-to-16V input source. The
LT8410/-1 controls power delivery by varying both the
peak inductor current and switch off time. This control
scheme results in low output voltage ripple as well as high efп¬Ѓciency over a wide load range. Figures 2 and 3 show …

Quiescent Current
Introduction Application Example
Figure 1 details the LT8410 boost
converter generating a 16V output
from a 2.5V-to-16V input source. The
LT8410/-1 controls power delivery by
varying both the peak inductor current and switch off time. This control
scheme results in low output voltage
ripple as well as high efficiency over a
wide load range. Figures 2 and 3 show
efficiency and output peak-to-peak
ripple for Figure 1вЂ™s circuit. Output
ripple voltage is less than 10mV despite the circuitвЂ™s small (0.1ВµF) output
capacitor.
The soft-start feature is implemented by connecting an external
capacitor to the VREF pin. If soft-start
is not needed, the capacitor can be
removed. Output voltage is set by a
resistor divider from the VREF pin to
ground with the center tap connected …

LвЂ‰DESIGN FEATURES Boost Converters for Keep-Alive

by Xiaohua Su
Quiescent Current
Introduction
Industrial remote monitoring systems
and keep-alive circuits spend most of
their time idle. Many of these systems
use batteries, so to maximize run time
power losses,even during low power
idle modes, must be minimized. Even
at no load, power supplies draw some
current to produce a regulated voltage
for keep-alive circuits.
The LT8410/-1 DC/DC boost
converter features ultralow quiescent
current and integrated high value
feedback resistors to minimize the
draw on the battery when electronics
are idle.
An entire boost converter takes very
little space, as shown in Figure 1. Ultralow Quiescent Current
Low Noise Boost Converter …
