TPS62000-HT

The TPS62000-HT is a low-noise synchronous step-down dc-dc converter that is ideally suited for systems powered from a 1-cell Li-ion battery or from a 2- to 3-cell NiCd, NiMH, or alkaline battery. The TPS62000-HT operates typically down to an input voltage of 1.8 V, with a specified minimum input voltage of 2 V.

Features of the TPS62000-HT are:(1)high-efficiency synchronous step-down converter with greater than 95% efficiency;(2)2 V to 5.5 V operating input voltage range;(3)adjustable output voltage range from 0.8 V to VI;(4)synchronizable to external clock signal up to 1 MHz;(5)up to 300 mA output current;(6)pin-programmable current limit;(7)high efficiency over a wide load current range in power save mode;(8)100% maximum duty cycle for lowest dropout;(9)low-noise operation antiringing switch and PFM/PWM operation mode;(10)internal softstart;(11)50-mA quiescent current (TYP);(12)evaluation module available for commercial temperature range.

The absolute maximum ratings of the TPS62000-HT can be summarized as:(1):the parameter is supply voltages on pin VIN and FC,the value is -0.3 to 6,the unit is V;(2):the parameter is voltages on pins EN, SYNC, FB, L,the value is -0.6 to VIN+0.3,the unit is V;(3):the parameter is peak switch current,the value is 1.6,the unit is A;(4):the parameter is operating ambient temperature,the value is -55 to 210,the unit is .
