TPS610985DSER Synchronous Boost Converter IC Chip with Ultra-Low Quiescent Current in WSON-6 Package

TPS610985DSER Integrated Circuit Chip 3V Ultra-Low Quiescent Current Synchronous Boost Converter WSON-6

The TPS610985 is an ultra-low power solution designed for products powered by either a one-cell or two-cell alkaline, NiCd or NiMH battery, a one-cell coin cell, or a one-cell Li-Ion or Li-polymer battery. It integrates either a Low-Dropout Linear Regulator (LDO) or a load switch with a boost converter, providing two output rails. The boost output V(MAIN) is designed as an always-on supply for the main system, while the LDO or load switch output V(SUB) powers peripheral devices.

• 300 nA ultra-low I_Q in low power mode
• Start-up into load at 0.7 V input voltage
• Operating input voltage from 0.7 V to 4.5 V
• Selectable output voltages up to 4.3 V
• Minimum 350 mA switch peak current limit
• Integrated LDO / load switch
• Two modes controlled by MODE pin:
  • Active mode: dual outputs at set values
  • Low power mode: LDO / load switch off; boost remains on
• Automatic pass-through
• Up to 88% efficiency at 10 µA load from 2 V to 3.3 V conversion (low power mode)
• Up to 93% efficiency at 5 mA to 100 mA load from 2 V to 3.3 V conversion
• 1.5 mm × 1.5 mm WSON package

• Smart remote controls
• BLE tags
• Wearable applications
• Low-power wireless applications
• Portable consumer or medical products
• Single-coin cell, single- or two-cell alkaline-powered applications
