FEATURES
DESCRIPTION
Efficiency > 90% at Nominal Operating
Conditions
The TPS6124x device is a high efficient synchronous
step up DC-DC converter optimized for products
Total DC Output Voltage Accuracy 5.0V±2%
powered by either a three-cell alkaline, NiCd or
Typical 30 mA Quiescent Current
NiMH, or one-cell Li-Ion or Li-Polymer battery. The
Best in Class Line and Load Transient
TPS6124x supports output currents up to 450mA.
Wide VIN Range From 2.3V to 5.5V
The TPS61240 has an input valley current limit of
500mA, and the TPS61241 has an input valley
Output current up to 450mA
current of 600mA.
Automatic PFM/PWM Mode transition
With an input voltage range of 2.3V to 5.5V the
Low Ripple Power Save Mode for Improved
device supports batteries with extended voltage

range and are ideal to power portable applications
Internal Softstart, 250ms typical Start-Up time
like mobile phones and other portable equipment.
The TPS6124x boost converter is based on a
3.5MHz Typical Operating Frequency
quasi-constant on-time valley current mode control

scheme.
Current Overload and Thermal Shutdown
The TPS6124x presents a high impedance at the
Protection
VOUT pin when shut down. This allows for use in
Three Surface-Mount External Components
applications that require the regulated output bus to

be driven by another supply while the TPS6124x is
Capacitors)
shut down.
Total Solution Size <13 mm2
During light loads the device will automatically pulse

currents.
In
the
shutdown
mode,
the
current
consumption is reduced to less than 1mA.
APPLICATIONS
TPS6124x allows the use of small inductors and
USB-OTG Applications
capacitors to achieve a small solution size. During
Portable HDMI Applications
shutdown, the load is completely disconnected from
the battery. The TPS6124x is available in a 6-pin
Cell Phones, Smart-Phones
WCSP and 2×2 SON package.
