PIN FUNCTIONS (TPS6128x) PIN I/O DESCRIPTION NAME NO. VIN A3, A4 I Power supply input. VOUT B3, B4 O Boost converter output. This is the enable pin of the device. On the rising edge of the enable pin, all the registers are reset with their default values. This input must not be left floating and must be terminated. EN = Low: The device is forced into shutdown mode. Depending on the logic level applied to the nBYP input, the converter can either be forced in pass-through mode or it's output can be regulated to EN A1 I a minimum level so as to limit the input-to-output voltage difference to less than 3.6V (typ). The current consumption is reduced to a few µA. For more details, refer to . EN = High: The device is operating normally featuring automatic dc/dc boost, pass-through mode transition. For more details, refer to . Power-Good Output (open-drain output to host): A logic high on the PG output indicates that the converter's output voltage is within its regulation limits. A logic low indicates a fault has occurred (e.g. PG A2 O thermal shutdown, output voltage out of limits, current limit triggered etc ...). The PG signal is de- asserted automatically once the IC resumes proper operation. VSEL signal is primarily used to set the output voltage dc/dc boost, pass-through threshold. This pin VSEL B1 I must not be left floating and must be terminated. A logic low level on the nBYP input forces the device in pass-through mode. For more details, refer nBYP C1 I to . This pin must not be left floating and must be terminated. This is the mode selection pin of the device. This pin must not be left floating, must be terminated and can be connected to AGND. During start-up this pin must be held low. Once the output voltage settled and PG pin indicates that the converter's output voltage is within its regulation limits the device can be forced in PWM mode operation by applying a high level on this pin. MODE B2 I 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. This pin must be held low during device start-up. MODE = High: Low-noise mode enabled, regulated frequency PWM operation forced. Inductor connection. Drain of the internal power MOSFET. Connect to the switched side of the SW C3, C4 I/O inductor. PGND D2, D3, D4 Power ground pin. AGND C2, D1 Analog ground pin. This is the signal ground reference for the IC.
