SLVSAO4 –DECEMBER 2010

3.5-MHz High Efficiency Step-Up Converter

Check for Samples: TPS61240-Q1

FEATURES

DESCRIPTION

•

Qualified for Automotive Applications

•

Efficiency > 90% at Nominal Operating

Conditions

The TPS61240-Q1 device is

high efficient

synchronous step up DC-DC converter optimized for

products powered by either a three-cell alkaline, NiCd

or NiMH, or one-cell Li-Ion or Li-Polymer battery. The

TPS6124x supports output currents up to 450mA.

The TPS61240-Q1 has an input valley current limit of

500mA.

•

Total DC Output Voltage Accuracy 5.0V±2%

Typical 30 mA Quiescent Current

Best in Class Line and Load Transient

Wide V_INRange From 2.3V to 5.5V

Output current up to 450mA

With an input voltage range of 2.3V to 5.5V the

device supports batteries with extended voltage

range and are ideal to power portable applications

like mobile phones and other portable equipment.

The TPS6124x boost converter is based on a

quasi-constant on-time valley current mode control

scheme.

Automatic PFM/PWM Mode transition

Low Ripple Power Save Mode for Improved

Efficiency at Light Loads

•

Internal Softstart, 250ms typical Start-Up time

3.5MHz Typical Operating Frequency

Load Disconnect During Shutdown

The TPS6124x presents a high impedance at the

V_OUTpin when shut down. This allows for use in

applications that require the regulated output bus to

be driven by another supply while the TPS6124x is

shut down.

Current Overload and Thermal Shutdown

Protection

•

Three Surface-Mount External Components

Required (One MLCC Inductor, Two Ceramic

Capacitors)

Total Solution Size <13 mm²

During light loads the device will automatically pulse

skip allowing maximum efficiency at lowest quiescent

currents. In the shutdown mode, the current

consumption is reduced to less than 1mA.

•

Available in a 2×2-SON Package

TPS6124x allows the use of small inductors and

capacitors to achieve a small solution size. During

shutdown, the load is completely disconnected from

the battery. The TPS6124x is available in a 2×2 SON

package.
