TPS62200DBV

The TPS6220x devices are a family of high-efficiency synchronous step-down converters ideally suited for portable systems powered by 1-cell Li-Ion or 3-cell NiMH/NiCd batteries.The TPS6220x needs only three small external components.Together with the tiny SOT23 package,a minimum system solution size can be achieved.An advanced fast response voltage mode control scheme achieves superior line and load regulation with small ceramic input and output capacitors.The TPS62200DBV belongs to TPS6220x devices.

Features of the TPS62200DBV are:(1)high efficiency synchronous step-down converter with up to 95% efficiency;(2)2.5 v to 6.0 v input voltage range;(3)adjustable output voltage range from 0.7 v to vi;(4)fixed output voltage options available;(5)up to 300 mA output current;(6)1 MHz fixed frequency pwm operation;(7)highest efficiency over wide load current range due to power save mode;(8)15-A typical quiescent current;(9)soft start;(10)100% duty cycle low-dropout operation;(11):dynamic output-voltage positioning;(12):availably in a tiny 5-pin sot23 package.

The absolute maximum ratings of the TPS62200DBV can be summarized as:(1):the supply voltages,VI is 0.3 V to 7.0 V;(2):the voltages on pins SW, EN, FB is 0.3 V to VCC +0.3 V;(3):the continuous power dissipation,PD is see dissipation rating table;(4):the operating junction temperature range,TJ is 40 to 85; (5):the storage temperature,Tstg is 65 to 150;(6):the lead temperature is 260.
