HIGH-EFFICIENCY, 1-CELL AND 2-CELL BOOST CONVERTERS

The converter output voltage can be adjusted from

FEATURES

1.5 V to a maximum of 3.3 V, by an external resistor

divider or, is fixed internally on the chip. The devices

provide an output current of 200 mA with a supply

voltage of only 0.9 V. The converter starts up into a

full load with a supply voltage of only 0.9 V and stays

in operation with supply voltages down to 0.8 V.

•

Integrated Synchronous Rectifier for Highest

Power Conversion Efficiency (>95%)

•

Start-Up Into Full Load With Supply Voltages

as Low as 0.9 V, Operating Down to 0.8 V

•

200-mA Output Current From 0.9-V Supply

Powersave-Mode for Improved Efficiency at

Low Output Currents

The converter is based on a fixed frequency, current

mode, pulse-width-modulation (PWM) controller that

goes automatically into power save mode at light

load. It uses a built-in synchronous rectifier, so, no

external Schottky diode is required and the system

efficiency is improved. The current through the switch

is limited to a maximum value of 1300 mA. The

converter can be disabled to minimize battery drain.

During shutdown, the load is completely isolated from

the battery.

•

Autodischarge Allows to Discharge Output

Capacitor During Shutdown

•

Device Quiescent Current Less Than 50 µA

Ease-of-Use Through Isolation of Load From

Battery During Shutdown of Converter

•

Integrated Antiringing Switch Across Inductor

Integrated Low Battery Comparator

An autodischarge function allows discharging the

output capacitor during shutdown mode. This is

especially useful when a microcontroller or memory is

supplied, where residual voltage across the output

capacitor can cause malfunction of the applications.

When programming the ADEN-pin, the autodischarge

function can be disabled. A low-EMI mode is im-

plemented to reduce interference and radiated elec-

tromagnetic energy when the converter enters the

discontinuous conduction mode. The device is pack-

aged in the micro-small space saving 10-pin MSOP

package. The TPS61010 is also available in a 3 mm

x 3 mm 10-pin QFN package.

Micro-Small 10-Pin MSOP or 3 mm x 3 mm

QFN Package

EVM Available (TPS6101xEVM-157)

APPLICATIONS

•

All Single- or Dual-Cell Battery Operated Prod-

ucts Like Internet Audio Players, Pager, Port-

able Medical Diagnostic Equipment, Remote

Control, Wireless Headsets

DESCRIPTION

The TPS6101x devices are boost converters intended

for systems that are typically operated from a single-

or dual-cell nickel-cadmium (NiCd), nickel-metal hy-

dride (NiMH), or alkaline battery.
