1 Features 3 Description

The TPS6122x family devices provide a power-supply 1• Up to 95% Efficiency at Typical Operating

solution for products powered by either a single-cell, Conditions two-cell, or three-cell alkaline, NiCd or NiMH, or one•

5.5 μA Quiescent Current cell Li-Ion or Li-polymer battery. Possible output

• Startup Into Load at 0.7 V Input Voltage currents depend on the input-to-output voltage ratio.

The boost converter is based on a hysteretic • Operating Input Voltage from 0.7 V to 5.5 V

controller topology using synchronous rectification to

• Pass-Through Function during Shutdown obtain maximum efficiency at minimal quiescent

• Minimum Switching Current 200 mA currents. The output voltage of the adjustable version

• Protections: can be programmed by an external resistor divider, or

is set internally to a fixed output voltage. The

– Output Overvoltage converter can be switched off by a featured enable

– Overtemperature pin. While being switched off, battery drain is

– Input Undervoltage Lockout minimized. The device is offered in a 6-pin SC-70

package (DCK) measuring 2 mm x 2 mm to enable • Adjustable Output Voltage from 1.8 V to 6 V

small circuit layout size.

• Fixed Output Voltage Versions

• Small 6-pin SC-70 Package
