TPS62590

The TPS62590 device is a synchronous dual step-down DC-DC converter optimized for battery powered portable applications. TPS62590 provides up to 1000-mA output current from batteries, such as single Li-Ion or other common chemistry AA and AAA cells.

Features of the TPS62590 are:(1)output current up to 600 mA;(2)VIN range from 2.5 V to 5.5 V;(3)output voltage accuracy in PWM mode ±2.5%;(4)typical 15-A quiescent current;(5)100% duty cycle for lowest dropout;(6)soft start;(7)available in a small TSOT, and 2 mm * 2 mm * 0.8 mm QFN package;(8)for improved features set, see TPS62290.

The absolute maximum ratings of the TPS62590 can be summarized as:(1):the symbol is VI,the parameter is input voltage range on VIN,the value is -0.3 to 7,the unit is V;(2):the symbol is VI,the parameter is voltage range on EN, MODE/DATA, DEF_1,the value is -0.3 to VIN +0.3, 7,the unit is V;(3):the symbol is VI,the parameter is voltage on SW,the value is -0.3 to 7,the unit is V;(4):the parameter is peak output current,the value is internally limited,the unit is A;(5):the symbol is Tj,the parameter is maximum operating junction temperature,the value is -40 to 125,the unit is ;(7):the symbol is Tstg,the parameter is storage temperature range,the value is -65 to 150,the unit is ;(8):the parameter is ESD rating HBM human-body model,the value is 2,the unit is kV;(9):the parameter is ESD rating CDM charged-device model,the value is 1,the unit is kV;(10):the parameter is ESD rating machine model,the value is 200,the unit is V.
