TPS54617

The TPS54617 low-input voltage high-output current synchronous buck PWM  converter offers the same features as the TPS54617 in a small package and higher switching frequency. The TPS54617 is available in a thermally enhanced 34 pin QFN (RUV) PowerPAD package, which eliminates bulky heatsinks.

Features of the TPS54617 are:(1)30-m MOSFET switches for high efficiency at 6-A continuous output;(2)adjustable output voltage down to 0.9 V with 1% accuracy;(3)externally compensated for design flexibility;(4)wide PWM frequency: fixed 350 kHz, 550 kHz or adjustable 280 kHz to 1.6 MHz;(5)synchronizable to 1.6MHz;(6)load protected by peak current limit and thermal shutdown;(7)small 3.5mm x 7mm package and similar layout to TPS54610 reduces board area and;(8)internally compensated for easy use and minimal component count total cost.

The absolute maximum ratings of the TPS54617 can be summarized as:(1):the parameter is input voltage range,the value is -0.3 to 7,the unit is V;(2):the parameter is output voltage range,the value is -0.6 to 7,the unit is V;(3):the parameter is source current,the value is 6,the unit is mA;(4):the parameter is sink current,the value is 10,the unit is mA;(5):the parameter is voltage differential,the value is ±0.3,the unit is V;(6):the parameter is operating junction temperature, TJ,the value is -40 to 125,the unit is ;(7):the parameter is storage temperature, Tstg,the value is -65 to 150,the unit is ;(8):the parameter is lead temperature 1,6 mm (1/16 inch) from case for 10 seconds,the value is 300,the unit is .
