TPS54620

The TPS54620 in thermally enhanced 3.5mm x 3.5mm QFN package is a full featured 17V, 6A synchronous step down converter which is optimized for small designs through high efficiency and integrating the high-side and low-side MOSFETs. Further space savings of TPS54620 are achieved through current mode control, which reduces component count, and by selecting a high switching frequency, reducing the inductor's footprint.

Features of the TPS54620 are:(1)integrated 26m / 19m MOSFETs;(2)split power rail: 1.6V to 17V on PVIN;(3)200kHz to 1.6MHz switching frequency;(4)synchronizes to external clock;(5)0.8V ±1% voltage reference over temperature;(6)low 2uA shutdown quiescent current;(7)monotonic start-up into pre-biased outputs;(8)40 to 150 operating junction temperature range;(9)adjustable slow start/power sequencing.

The absolute maximum ratings of the TPS54620 can be summarized as:(1):the parameter is input voltage range,the value is -0.3 to 20,the unit is V;(2):the parameter is output voltage range,the value is 0 to 7,the unit is V;(3):the parameter is source current,the value is ±100,the unit is A;(4):the parameter is sink current,the value is ±200,the unit is A;(5):the parameter is electrostatic discharge,the value is 2,the unit is kV;(6):the parameter is operating junction temperature, TJ,the value is -40 to 150,the unit is ;(7):the parameter is storage temperature, Tstg,the value is -65 to 150,the unit is .
