DESCRIPTION
The TPS6103x devices provide a power supply
solution for products powered by either a one-cell
Li-Ion or Li-polymer, or a two to three-cell alkaline,
NiCd or NiMH battery. The converter generates a
stable output voltage that is either adjusted by an
external resistor divider or fixed internally on the chip.
It provides high efficient power conversion and is
capable of delivering output currents up to 1 A at 5 V
at a supply voltage down to 1.8 V. The implemented
boost converter is based on a fixed frequency,
pulse-width- modulation (PWM) controller using a
synchronous rectifier to obtain maximum efficiency.
At low load currents the converter enters Power Save
mode to maintain a high efficiency over a wide load
current range. The Power Save mode can be dis-
abled, forcing the converter to operate at a fixed
switching frequency. It can also operate synchronized
to an external clock signal that is applied to the
SYNC pin. The maximum peak current in the boost
switch is limited to a value of 4500 mA.

96% EFFICIENT SYNCHRONOUS BOOST CONVERTER WITH 4A SWITCH
The converter can be disabled to minimize battery
drain. During shutdown, the load is completely dis-
connected from the battery. A low-EMI mode is
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).
