The TPS6100x devices are boost converters intended for systems that are typically operated from a single- or dual-cell nickel-cadmium (NiCd), nickel-metal hydride (NiMH), or alkaline battery. The converter output voltage can be adjusted from 1.5 V to a maximum of 3.3 V and provides a minimum output current of 100 mA from a single battery cell and 250 mA from two battery cells. The converter starts up into a full load with a supply voltage of 0.9 V and stays in operation with supply voltages as low as 0.8 V.
The converter is based on a fixed-frequency, current-mode pulse-width-modulation (PWM) controller that goes into power-save mode at low load currents. The current through the switch is limited to a maximum of 1100 mA, depending on the output voltage. The current sense is integrated to further minimize external component count. The converter can be disabled to minimize battery drain when the system is put into standby.
A low-EMI mode is implemented to reduce interference and radiated electromagnetic energy that is caused by the ringing of the inductor when the inductor discharge-current decreases to zero. The device is packaged in the space-saving 10-pin MSOP package.

NAME | NO. | ||
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 (TPS61000, TPS61002, TPS61003, TPS61004, TPS61005, TPS61006), leave the FB pin unconnected. |
NC/FBGND | 8 | — | Not connected (TPS61000, TPS61002, TPS61003, TPS61004, TPS61005, TPS61006). A ground pin for the feedback resistor divider for the TPS61007 only. |
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 pullup resistor should be connected between LBO and VOUT. |
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. |
