TPS61240

The TPS61240 device is a high efficient synchronous step up DC-DC converter optimized for products powered by either a three-cell alkaline, NiCd or NiMH, or one-cell Li-Ion or Li-Polymer battery.
 
Features of the TPS61240 are:(1)efficiency > 90% at nominal operating conditions;(2)total DC output voltage accuracy 5.0V±2%;(3)typical 30 mA quiescent current;(4)best in class line and load transient;(5)wide VIN range from 2.3V to 5.5V;(6)output current up to 450mA;(7)automatic PFM/PWM mode transition;(8)low ripple power save mode for improved efficiency at light loads;(9)internal softstart, 250ms typical start-up time;(10)3.5MHz typical operating frequency;(11)load disconnect during shutdown;(12)current overload and thermal shutdown protection;(13)three surface-mount external components required (one MLCC inductor, two ceramic capacitors);(14)total solution size <13 mm2;(15)available in a 6-pin WCSP and 2*2-SON package.

The absolute maximum ratings of the TPS61240 can be summarized as:(1):the symbol is VI,the parameter is input voltage range on VIN, L, EN,the value is -0.3 to 7,the unit is V;(2):the parameter is voltage on VOUT,the value is -2.0 to 7,the unit is V;(3):the parameter is voltage on FB,the value is -2.0 to 14,the unit is V;(4):the parameter is peak output current,the value is internally limited;(5):the symbol is Tj,the parameter is maximum operating junction temperature,the value is -40 to 125,the unit is ;(6):the symbol is Tstg,the parameter is storage temperature range,the value is -65 to 150,the unit is ;(7):the parameter is ESD rating HBM human-body model,the value is 4,the unit is kV;(8):the parameter is ESD rating CDM charged-device model,the value is 500,the unit is kV;(9):the parameter is ESD rating machine model,the value is 200,the unit is V.
