TPS54917

The TPS54917 is available in a thermally enhanced 34 pin QFN (RUV) PowerPAD package, which eliminates bulky heatsinks. TI TPS54917 provides evaluation modules and the SwitcherPro™ design software tool to aid in achieving high-performance power supply designs to meet aggressive equipment development cycles.

Features of the TPS54917 are:(1)13-m MOSFET switches for high efficiency at 9-A continuous output;(2)adjustable output voltage down to 0.9V 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 TPS54910 reduces board area and total cost.

The absolute maximum ratings of the TPS54917 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 voltage differential,the value is ±0.3,the unit is V;(5):the parameter is operating junction temperature, TJ,the value is -40 to 150,the unit is ;(6):the parameter is storage temperature, Tstg,the value is -65 to 150,the unit is .
