When connected to a low level (lower than 0.4V) the device stops working. When high (higher than 1.3V) the device is enabled. 2 COMP Error amplifier output. A compensation network has to be connected to this pin. Usually a 220pF capacitor is enough to guarantee the loop stability. 3 VFB Error amplifier inverting input. The output voltage can be adjusted from 0.6V up to the input voltage by connecting this pin to an external resistor divider. 4 GND Ground. 5 LX Switch output node. This pin is internally connected to the drain of the internal switches. 6 VCC Input voltage. The start up input voltage is 2.2V (typ) while the operating input voltage range is from 2V to 5.5V. An internal UVLO circuit realizes a 100mV (typ.) hysteresis. 7 SYNC Operating mode selector input. When high (higher than 1.3V) the Low Consumption Mode is selected. When low (lower than 0.5V) the Low Noise Mode is selected. If connected with an appropriate external synchronization signal (from 500KHz up to 1.4MHz) the internal synchronization circuit is activated and the device works at the same switching frequency. 8 PGOOD Power good comparator output. It is an open drain output. A pull-up resistor should be connected between PGOOD and VOUT (or VCC depending on the requirements). The pin is forced low when the output voltage is lower than 90% of the regulated output voltage and goes high when the output voltage is greater than 90% of the regulated output voltage. If not used the pin can be left floating. RUN COMP VFB GND 1 3 2 4LX VCC SYNC PGOOD 8 7 6 5 D01IN1239AMOD |
