TPS61220

The TPS61220 devices provide a power-supply solution for products powered by either a single-cell, two-cell, or three-cell alkaline, NiCd or NiMH, or one-cell Li-Ion or Li-polymer battery. Possible output currents depend on the input-to-output voltage ratio.

Features of the TPS61220 are:(1)up to 95% efficiency at typical operating conditions;(2)5.5 mA quiescent current;(3)startup into load at 0.7 V input voltage;(4)operating input voltage from 0.7 V to 5.5 V;(5)pass-through function during shutdown;(6)minimum switching current 200 mA;(7)adjustable output voltage from 1.8 V to 5.5 V;(8)fixed output Voltage versions;(9)small 6-pin SC-70 package.

The absolute maximum ratings of the TPS61220 can be summarized as:(1):the symbol is VI,the parameter is input input voltage range on VIN, L, VOUT, EN, FB,the value is -0.3 to 7.5,the unit is V;(2):the symbol is Tj,the parameter is maximum operating junction temperature,the value is -40 to 150,the unit is ;(3):the symbol is Tstg,the parameter is storage temperature range,the value is -65 to 150,the unit is ;(4):the symbol is ESD,the parameter is human body model (HBM),the value is 2,the unit is kV;(5):the symbol is ESD,the parameter is machine model (MM),the value is 200,the unit is V;(6):the symbol is ESD,the parameter is charged device model (CDM),the value is 1.5,the unit is kV.
