TPS61220DCKR Description
Devices from the TPS61220DCKR family offer a power-supply solution
for products that use one cell Li-Ion or Li-polymer or two or three
alkaline, NiCd, or NiMH batteries. The input-to-output voltage
ratio affects the potential output currents. The boost converter
uses synchronous rectification to achieve optimum efficiency at the
lowest possible quiescent currents. It is based on a hysteretic
controller topology. The adjustable version's output voltage can
either be preset using an external resistor divider or fixed
internally.
TPS61220DCKR Features
Adjustable Output Voltage from 1.8 V to 6 V
Up to 95% Efficiency at Typical Operating Conditions
Operating Input Voltage from 0.7 V to 5.5 V
Startup Into Load at 0.7 V Input Voltage
Pass-Through Function during Shutdown
Minimum Switching Current 200 mA
TPS61220DCKR Applications
Solar or Fuel Cell Powered Applications
Consumer and Portable Medical Products
Personal Care Products
White or Status LEDs
