Check for Samples: TPS61030, TPS61031, TPS61032

FEATURES

DESCRIPTION

• 96% Efficient Synchronous Boost Converter

The TPS6103x devices provide a power supply

With 1000-mA Output Current From 1.8-V

solution for products powered by either a one-cell

Input

Li-Ion or Li-polymer, or a two to three-cell alkaline,

• Device Quiescent Current: 20-µA (Typ)

NiCd or NiMH battery. The converter generates a

• Input Voltage Range: 1.8-V to 5.5-V

stable output voltage that is either adjusted by an

external resistor divider or fixed internally on the chip.

• Fixed and Adjustable Output Voltage Options

It provides high efficient power conversion and is

Up to 5.5-V

capable of delivering output currents up to 1 A at 5 V

• Power Save Mode for Improved Efficiency at

at a supply voltage down to 1.8 V. The implemented

Low Output Power

boost converter is based on a fixed frequency,

pulse-width- modulation (PWM) controller using a

• Low Battery Comparator

synchronous rectifier to obtain maximum efficiency.

• Low EMI-Converter (Integrated Antiringing

At low load currents the converter enters Power Save

Switch)

mode to maintain a high efficiency over a wide load

• Load Disconnect During Shutdown

current range. The Power Save mode can be

disabled, forcing the converter to operate at a fixed

• Over-Temperature Protection

switching frequency. It can also operate synchronized

• Available in a Small 4 mm x 4 mm QFN-16 or in

to an external clock signal that is applied to the

a TSSOP-16 Package

SYNC pin. The maximum peak current in the boost

switch is limited to a value of 4500 mA.

APPLICATIONS

The converter can be disabled to minimize battery

• All Single Cell Li or Dual Cell Battery Operated

drain. During shutdown, the load is completely

Products as MP-3 Player, PDAs, and Other

disconnected from the battery. A low-EMI mode is

Portable Equipment

implemented to reduce ringing and, in effect, lower

radiated electromagnetic energy when the converter

enters the discontinuous conduction mode.

The device is packaged in a 16-pin QFN package

measuring 4 mm x 4 mm (RSA) or in a 16-pin

TSSOP PowerPAD

package (PWP).

To enable power save, SYNC must be set low. Power save mode is used to improve efficiency at light load. In power save mode the converter only operates when the output voltage trips below a set threshold voltage.

TPS61030 TPS61031, TPS61032 SLUS534E – SEPTEMBER 2002 – REVISED JANUARY 2012 www.ti.com APPLICATION INFORMATION Design Procedure The TPS6103x dc/dc converters are intended for systems powered by a dual or triple cell NiCd or NiMH battery with a typical terminal voltage between 1.8 V and 5.5 V. They can also be used in systems powered by one-cell Li-Ion with a typical stack voltage between 2.5 V and 4.2 V.

TPS61030 TPS61031, TPS61032 SLUS534E – SEPTEMBER 2002 – REVISED JANUARY 2012 www.ti.com The output of the low battery supervisor is a simple open-drain output that goes active low if the dedicated battery voltage drops below the programmed threshold voltage on LBI. The output requires a pullup resistor with a recommended value of 1 MΩ. The maximum voltage which is used to pull up the LBO outputs should not exceed the output voltage of the dc/dc converter.

TPS61030 TPS61031, TPS61032 SLUS534E – SEPTEMBER 2002 – REVISED JANUARY 2012 www.ti.com Capacitor Selection Input Capacitor At least a 10-µF input capacitor is recommended to improve transient behavior of the regulator and EMI behavior of the total power supply circuit. A ceramic capacitor or a tantalum capacitor with a 100-nF ceramic capacitor in parallel, placed close to the IC, is recommended.
