SLVSAQ2C – JANUARY 2014 – REVISED OCTOBER 2014 TPS6123x High Efficiency Synchronous Step Up Converters with 5-A Switches
1 Features 3 Description The TPS6123x device family is a high efficiency
synchronous step up converter with compact solution
size. It is optimized for products powered by a onecell Li-Ion battery, or a regulated power rail of 3.3 V.
The IC integrates a 5-A switch and is capable of
delivering output currents up to 2.1 A at a 5-V output
with a 3.3-V input supply. The device is based on a
quasi-constant on-time valley current mode control
scheme. The typical operating frequency is 2 MHz,
which allows the use of small inductors and
capacitors to achieve a small solution size. The
TPS61230 and TPS61231 provide an adjustable
output voltage via an external resistor divider, and the
TPS61232 provides a fixed output voltage of 5 V. 1 Input Voltage Range: 2.3 V to 5.5 V
Output Voltage Range: 2.5 V to 5.5 V
Up to 96% Efficiency Synchronous Boost
