Tiny Step-Up/Step-Down Power Supply Delivers 3.3V at 1.3A in
Battery-Powered Devices вЂ“ Design Note 271
Keith Szolusha
Introduction
Many of todayвЂ™s cellular phones, PDAs, MP3 players and
other portable devices require that a consistent 3.3V
power supply be delivered from a single, rechargeable
lithium-ion battery. The problem is that a Li-Ion battery
at full charge has a voltage somewhat higher than 3.3V
and loses voltage over the life of a charge to less than
3.3V. A power supply that depends on a Li-Ion requires
a voltage regulator that can maintain consistent 3.3V
output from both high and low inputs. Since typical
Li-Ion applications are portable mass-market devices
where the focus is on short time-to-market, long battery
life, small size and low cost, the regulator must take
minimal space, be highly efп¬Ѓcient and use inexpensive
off-the-shelf components wherever possible. Regulated Output Voltage from a Range of Inputs
Although a SEPIC is only one of many possible conп¬Ѓgurations for a DC/DC converter, it has a major advantage
over other choices when applied in a modern portable
device. The SEPIC in Figure 1 delivers 3.3V output
throughout the input voltage range, 2.7V to 4.2V. One
alternative to the SEPIC conп¬Ѓguration is a simple stepdown converter. A step-down converter delivers 3.3V …
