TPS61251

The TPS61251 device provides a power supply solution for products powered by either a three-cell, NiCd or NiMH battery, or a one-cell Li-Ion or Li-polymer battery. The wide input voltage range of TPS61251 is ideal to power portable applications like mobile phones, solid state drives (SSD) and wireless modems.

Features of the TPS61251 are:(1)resistor programmable input current limit;(2)snooze mode draws only 2 mA (typ.) quiescent current;(3)designed to charge large capacitor values in the farad range;(4)up to 92% efficiency;(5)power good indicates appropriate output voltage level even in shut down;(6)VIN range from 2.3V to 6.0V;(7)adjustable output voltage up to 6.5V;(8)100% duty-cycle mode when VIN > VOUT;(9)load disconnect and reverse current protection;(10)short circuit protection;(11)typical operating frequency 3.5 MHz;(12)available in a 2*2-mm QFN-8 package.

The absolute maximum ratings of the TPS61251 can be summarized as:(1):the parameter is voltage range,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 2,the unit is kV;(5):the symbol is ESD,the parameter is charge device model - (CDM),the value is 0.5,the unit is kV.
