Add R suffix to device type (e.g. TPS61000DGSR) to order quantities of 3000 devices per reel. Terminal Functions TERMINAL I/O DESCRIPTION NAME NO. I/O DESCRIPTION COMP 2 Compensation of error amplifier. Connect R-C-C network to set frequency response of control loop. See the Application section for more details. EN 1 I Chip-enable input. The converter is switched on if EN is set high and is switched off when EN is connected to ground (shutdown mode). FB 3 I Feedback input for adjustable output voltage (TPS61000 only). The output voltage is programmed depending on the values of resistors R1 and R2. For the fixed output voltage versions (TPS61001, 2, 3, 4, 5, 6), leave the FB pin unconnected. GND 4 Ground LBI 9 I Low-battery detector input. A low-battery signal is generated at the LBO pin when the voltage on LBI drops below the threshold of 500 mV. Connect LBI to GND or VBAT if the low-battery detector function is not used. Do not leave this pin floating. LBO 10 O Open-drain low-battery detector output. This pin is pulled low if the voltage on LBI drops below the threshold of 500 mV. A pull-up resistor should be connected between LBO and VOUT. NC 8 Not connected SW 7 I Switch input pin. The node between inductor and anode of the rectifier diode is connected to this pin. VBAT 6 I Supply pin VOUT 5 O Output voltage. For the fixed output voltage versions, the integrated resistive divider is connected to this pin. 1 2 3 4 5 10 9 8 7 6 EN COMP FB GND VOUT LBO LBI NC SW VBAT DGS PACKAGE (TOP VIEW) |
