DESCRIPTION
The TPS6126x devices provide a power supply solution for products powered by either single or dual cell
alkaline, NiCd or NiMH battery. Its unique advanced softstart makes it also suitable for products powered by high
output impedance battery types, like coin cells. Output currents can go as high as 100 mA while using a single
cell alkaline battery, and discharge it down to 0.8 V or lower. The boost converter is based on a quasi 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 ensure high efficiency over a wide
load current range. The maximum average current in the switches is limited to a programmable value which can
go as high as 700 mA. The output voltage is programmable using an external resistor divider, or is fixed
internally on the chip. In addition to that the average output current can be programmed as well. The converter
will then regulate the programmed output voltage or the programmed output current which ever demands lower
output power. The converter can be disabled to minimize battery drain. During shutdown, the load is
disconnected from the battery. The device is packaged in a 6-pin SON PowerPAD
package measuring 2 × 2
mm (DRV).
