TPS61200

The TPS61200 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. TPS61200 is also used in fuel cell or solar cell powered devices where the capability of handling low input voltages is essential.

Features of the TPS61200 are:(1)more than 90% efficiency;(2)automatic transition between boost mode and down conversion mode;(3)device quiescent current less than 55 mA;(4)startup into full load at 0.5 V input voltage;(5)operating input voltage range from 0.3 V to 5.5 V;(6)programmable undervoltage lockout threshold;(7)output short circuit protection under all operating conditions;(8)fixed and adjustable output voltage options from 1.8 V to 5.5 V;(9)power save mode for improved efficiency at low output power;(10)forced fixed frequency operation possible;(11)load disconnect during shutdown;(12)overtemperature protection;(13)small 3 mm x 3 mm QFN-10 package.

The absolute maximum ratings of the TPS61200 can be summarized as:(1):the symbol is VI,the parameter is input voltage range on VIN, L, VAUX, VOUT, PS, EN, FB, UVLO,the value is -0.3 to 7,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 4,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.
