3 Description
The TPS6120x devices provide a power supply
solution for products powered by either a single-cell,
two-cell, or three-cell alkaline, NiCd or NiMH, or one-
cell Li-Ion or Li-polymer battery. It is also used in fuel
cell or solar cell powered devices where the capability
of handling low input voltages is essential. Possible
output currents depend on the input to output voltage
ratio. The devices provide output currents of up to
600 mA at a 5-V output, while using a single-cell Li-
Ion or Li-Polymer battery and discharges it down to
2.6 V. The 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
the Power Save mode to maintain a 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 average
input current is limited to a maximum value of 1500
mA. The output voltage is programmed by 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 completely
disconnected from the battery. The device is
packaged in a 10-pin VSON package measuring 3
mm x 3 mm.
