Table 5. Electrical Characteristics (Tj = 25°C, VCC = 3.6V unless otherwise specified)
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.
