VOUT A1 O Power output pin. Apply output load between this pin and GND. VIN A2, A3 I The VIN pins supply current to the TPS8267x internal regulator. EN B2 I This is the enable pin of the device. Connect this pin to ground to force the converter into shutdown mode. Pull this pin to VI to enable the device. This pin must not be left floating and must be terminated. MODE B1 I This is the mode selection pin of the device. This pin must not be left floating and must be terminated. MODE = LOW: The device is operating in regulated frequency pulse width modulation mode (PWM) at high-load currents and in pulse frequency modulation mode (PFM) at light load currents. MODE = HIGH: Low-noise mode is enabled and regulated frequency PWM operation is forced. GND C1, C2, C3 – Ground pin. (1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) All voltage values are with respect to network ground terminal. (3) Operation above 4.8V input voltage for extended periods may affect device reliability. (4) In applications where high power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature may have to be derated. Maximum ambient temperature (TA(max)) is dependent on the maximum operating temperature (TINT(max)), the maximum power dissipation of the device in the application (PD(max)), and the junction-to-ambient thermal resistance of the part/package in the application (RθJA), as given by the following equation: TA(max)= TJ(max)–(RθJA X PD(max)). To achieve optimum performance, it is recommended to operate the device with a maximum internal temperature of 105°C. 8 Specifications 8.1 Absolute Maximum Ratings over operating free-air temperature range (unless otherwise noted) (1) MIN MAX UNIT VI (2) Voltage at VIN(3) –0.3 6 V Voltage at VIN (TPS826721) (3) -0.3 5.5 Voltage at VOUT –0.3 3.6 V Voltage at EN, MODE –0.3 VIN + 0.3 V Power dissipation Internally limited TA Operating temperature range(4) –40 85 °C TINT (max) Maximum internal operating temperature 125 °C Tstg Storage temperature –55 125 °C |
