TPS65230A2DCAR

The TPS65230A2DCAR is a kind of power management IC. TPS65230A2DCAR includes one PWM buck controller, two adjustable, synchronous buck regulators, two independent USB power switches and a supply voltage supervisor (SVS) to provide main power functions for the applications such as digital set top boxes, xDSL & cable modems, DVD players, home gateway and access point networks, wireless routers.

There are some features of TPS65230A2DCAR as follows. (1) wide input supply voltage range (10.8 to 22 V); (2) early supply failure flag (open drain output) is set when input voltage drops below 9.3 V; (3) early temperature warning flag (open drain output) is set if temperature approaches shut-down threshold; (4) supply voltage supervisor circuit with two monitor inputs and open drain output; (5) over current protection on all rails; (6) thermal shutdown to protect device during excessive power dissipation.

The following is about the absolute maximum ratings of TPS65230A2DCAR over operating free-air temperature range (unless otherwise noted). (1): input voltage range at VIN is from -0.3 to 25 V; (2): input voltage range at VINB, VINBQ, VINU is from -0.3 to 7.0 V; (3): voltage range at INT is from -0.3 to 7.0 V; (4): output current BUCK2, BUCK3 is 3.8 A; (5): peak output current is internally limited; (6): ESD rating is 2 kV for human body model (HBM) and 500 V for charged device model (CDM); (7): JA (thermal resistance-junction to ambient) is 25/W; (8): TA (operating ambient temperature) is from 0 to 85; (9): TJ (operating virtual junction temperature range) is from 0 to 150; (10): TSTG (storage temperature range) is from -65 to 150.
