TPS54354-EP

The TPS54354-EP is a medium-output-current synchronous buck PWM converter with an integrated high-side MOSFET and a gate driver for an optional low-side external MOSFET.

Features of the TPS54354-EP are:(1)100-m, 4.5-A peak MOSFET switch for high efficiency at 3-A continuous output current;(2)use external low-side MOSFET or diode;(3)fixed-output versions;(4)internally compensated for low parts count;(5)synchronize to external clock;(6)180°out-of-phase synchronization;(7)wide pulse width modulation (PWM);(8)internal slow start;(9)load protected by peak current limit and thermal shutdown;(10)adjustable undervoltage lockout;(11)16-pin powerPAD thin shrink small-outline package (TSSOP) (PWP).

The absolute maximum ratings of the TPS54354-EP can be summarized as:(1):the parameter is input voltage range,the value is -0.3 to 21.5,the unit is V;(2):the parameter is output voltage range,the value is -0.3 to 8.5,the unit is V;(3):the parameter is source current,the value is 10,the unit is mA;(4):the parameter is sink current,the value is 100,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 -55 to 150,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 in) from case for 10 s,the value is 260,the unit is .
