TPS6040x Unregulated 60-mA Charge Pump Voltage Inverter Features 3 Description

The TPS6040x family of devices generates an Inverts Input Supply Voltage unregulated negative output voltage from an input• Upto 60-mA Output Current voltage ranging from 1.6Vto 5.5V. The devices are• Only Three Small 1-µF Ceramic Capacitors typically suppliedbya preregulated supply railof5V
Needed or 3.3V. Duetoits wide input voltage range, twoor
three NiCd, NiMH,or alkaline battery cells,as wellas• Input Voltage Range From 1.6Vto 5.5V one Li-Ion cell can also power them.• PowerSave-Mode for Improved Efficiencyat Low-
Only three external 1-µF capacitors are requiredtoOutput Currents (TPS60400)
