The internal threshold is set to 0.6V. The external threshold can be adjusted by using an external resistor divider. 2 COMP Error amplifier output. Compensate it with a 220pF capacitor 3 VFB Error amplifier input. The output voltage can be adjusted by using an external resistor divider connected to this pin (VFB = 0.6V). 4 GND Ground. 5 LX Switch node connection to the inductor. 6 VCC Input voltage. 7 SYNC This pin allows to select Low Noise/ Low Consumption Mode or to sychronize the device. 8 LBO Battery low voltage detector output. If the voltage at the LBI pin drops below the internal thrshold, LBO goes low. The LBO is an open drain output. A pull_up resistor should be connected between the pin and the output voltage LBI COMP VFB GND 1 3 2 4LX VCC SYNC LBO 8 7 6 5 D01IN1239A/mod |
