Manufacturer: Texas Instruments

Overview: Product Folder Sample & Buy Technical Documents Tools & Software Support & munity TLV61220 SLVSB53A – MAY 2012 – REVISED DECEMBER 2014 TLV61220 Low-Input Voltage Step-Up Converter in Thin SOT-23 Package.

General Description

The TLV61220 device provides a power-supply solution for products powered by either a single-cell, two-cell, or three-cell alkaline, NiCd or NiMH, or onecell Li-Ion or Li-polymer battery.

Possible output currents depend on the input-to-output voltage ratio.

The boost converter is based on a hysteretic controller topology using synchronous rectification to obtain maximum efficiency at minimal quiescent currents.

Key Features

  • 1 Up to 95% Efficiency at Typical Operating Conditions.
  • 5.5-μA Quiescent Current.
  • Startup Into Load at 0.7-V Input Voltage.
  • Operating Input Voltage from 0.7 V to 5.5 V.
  • Pass-Through Function during Shutdown.
  • Minimum Switching Current 200 mA.
  • Protections:.
  • Output Overvoltage.
  • Overtemperature.
  • Input Undervoltage Lockout.
  • Adjustable Output Voltage from 1.8 V to 5.5 V.
  • Small 6-pin Thin SOT-23.
