• Forced Fixed Frequency Operation and

go as high as 600 mA while using a single-cell Li-Ion

Synchronization Possible

or Li-Polymer Battery, and discharge it down to 2.5V

or lower. The buck-boost converter is based on a

• Over-Temperature Protection

controller using synchronous rectification to obtain

• Available in Small 2.5mm × 2.5mm, QFN-10

maximum efficiency. At low load currents, the

Package

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 1000 mA. 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 QFN PowerPAD™ package

measuring 2.5mm × 2.5 mm (DSK).

TPS63030 TPS63031 www.ti.com SLVS696B – OCTOBER 2008 – REVISED MARCH 2012 DETAILED DESCRIPTION CONTROLLER CIRCUIT The controlling circuit of the device is based on an average current mode topology. The average inductor current is regulated by a fast current regulator loop which is controlled by a voltage control loop. The controller also uses input and output voltage feedforward.

TPS63030 TPS63031 SLVS696B – OCTOBER 2008 – REVISED MARCH 2012 www.ti.com Device Enable The device is put into operation when EN is set high. It is put into a shutdown mode when EN is set to GND. In shutdown mode, the regulator stops switching, all internal control circuitry is switched off, and the load is disconnected from the input. This also means that the output voltage can drop below the input voltage during shutdown.

TPS63030 TPS63031 www.ti.com SLVS696B – OCTOBER 2008 – REVISED MARCH 2012 LAYOUT CONSIDERATIONS As 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.
