TPS62004-Q1

The TPS62004-Q1 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 TPS62004-Q1 operates typically down to an input voltage of 1.8 V, with a specified minimum input voltage of 2 V.

Features of the TPS62004-Q1 are:(1)qualified for automotive applications;(2)high-efficiency synchronous step-down converter with greater than 95% efficiency;(3)adjustable output voltage range from 0.8 V to VI;(4)fixed output voltage options available in;(5)2-V to 5.5-V operating input voltage range;(6)synchronizable to external clock signal up to 1 MHz;(7)up to 600-mA output current;(8)pin-programmable current limit;(9)high efficiency over a wide load current range in power save mode;(10)100% maximum duty cycle for lowest dropout;(11)low-noise operation antiringing switch and PFM/PWM operation mode;(12)internal softstart;(13)50-A quiescent current (TYP);(14)available in the 10-pin microsmall outline package (MSOP);(15)evaluation module available.

The absolute maximum ratings of the TPS62004-Q1 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 -40 to 150,the unit is ;(5):the parameter is storage temperature range, Tstg,the value is -65 to 150,the unit is ;(6):the parameter is lead temperature (soldering, 10 sec),the value is 260,the unit is .
