Operating Conditions: V
COMP1/2
COMP1/2
based on internal oscillator clock frequency
IPGOOD = 2mA
FS_SYNC pin: resistor to GND; see Figure 12 for curves
RL = 10kΩ to ground; (Note 5)
CL = 100pF, RL = 10kΩ to ground; (Note 5)
CL = 100pF, RL = 10kΩ to ground; (Note 5)
COMP1/2 to FB1/2; compare to internal VREF/REFIN
RL = 10kΩ to ground; (may trip short-circuit)
Causes PGOOD to go low; if there for a filter time,
Implies the COMP pin(s) is out -of-range, and shuts down IC
(nominal 300kHz = 3.3µs clock period)
(As determined by resistor divider into FB3)
DRIVE3 to FB3; compare to internal VREF
1.1µF max capacitance
Determined by REFIN voltage
To select 0 degree phase; see Table 1
