Description
The TPS6014x step-up, regulated charge pumps generate a 5-V ±4% output voltage from a 1.8-V to 3.6-V input voltage range. The devices are typically powered by two alkaline, NiCd, or NiMH battery cells and provide an output current of minimum 100 mA from a 2-V input. Only four external capacitors are needed to build a complete voltage tripler charge pump.

Features
• Regulated 5 V ±4% Output Voltage
• Up to 100-mA Output Current
• 1.8-V to 3.6-V Input Voltage Range
• 65-µA Quiescent Supply Current
• 0.05-µA Shutdown Current, Battery Is Isolated From Load in Shutdown
• Integrated Low-Battery or Power-Good Indicator
• Low-Output Voltage Ripple Over Complete Output Current Range
• Easy-to-Design With Low-EMI Power Supply Because No Inductors Are Required
• Evaluation Module Available (TPS60140EVM-144)
• Available in a 6.5-mm × 4.4-mm 20-Pin HTSSOP Package

Applications
• Replacement of DC-DC Converters With Inductors in Battery-Powered Applications:
    – Two Battery Cells to 5-V Conversions
    – Portable Instruments
    – Miniature Equipment
    – Backup-Battery Boost Converters
    – Medical Instruments
    – 5-V Smart Card Supplies
