DESCRIPTION

The TPS6306x devices provide a power supply solution for products powered by either three-cell up to six-cell

alkaline, NiCd or NiMH battery, or a one-cell or dual-cell Li-Ion or Li-polymer battery. Output currents can go as

high as 2A while using a dual-cell Li-Ion or Li-Polymer Battery, and discharge it down to 5V or lower. The

buck-boost converter is based on a fixed frequency, pulse-width-modulation (PWM) controller using synchronous

rectification to obtain maximum efficiency. At low load currents, the converter enters Power Save mode to

maintain high efficiency over a wide load current range. The Power Save mode can be disabled, forcing the

converter to operate at a fixed switching frequency. The maximum average current in the switches is limited to a

typical value of 2.25A. The output voltage is programmable using an external resistor divider, or is fixed internally

on the chip. The converter can be disabled to minimize battery drain. During shutdown, the load is disconnected

from the battery. The device is packaged in a 10-pin SON PowerPAD™ package measuring 3mm × 3mm (DSC).

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

The controller also uses input and output voltage feedforward. Changes of input and output voltage are monitored and immediately can change the duty cycle in the modulator to achieve a fast response to those errors. The voltage error amplifier gets its feedback input from the FB pin.

Average Current Mode Control Power-save mode and synchronization The PS/SYNC pin can be used to select different operation modes. Power Save Mode is used to improve efficiency at light load. To enable Power-Save, PS/SYNC must be set low. If PS/SYNC is set low then Power Save Mode is entered when the average inductor current gets lower then about 100mA.

When in operation, the device automatically enters the shutdown mode if the voltage on VIN drops below the undervoltage lockout threshold.

TPS63060 TPS63061 SLVSA92A – DECEMBER 2011 – REVISED FEBRUARY 2012 www.ti.com APPLICATION INFORMATION DESIGN PROCEDURE The TPS6306x series of buck-boost converter has internal loop compensation. Therefore, the external L-C filter has to be selected to work with the internal compensation. When selecting the output filter a low limit for the inductor value exists to avoid subharmonic oscillation which could be caused by a far too fast ramp up of the amplified inductor current.

TPS63060 TPS63061 SLVSA92A – DECEMBER 2011 – REVISED FEBRUARY 2012 www.ti.com LAYOUT CONSIDERATIONS For all switching power supplies, the layout is an important step in the design, especially at high peak currents and high switching frequencies. If the layout is not carefully done, the regulator could show stability problems as well as EMI problems. Therefore, use wide and short traces for the main current path and for the power ground tracks.
