Current sense input pin. Voltage generated across an external sense
resistor is fed into this pin.
Compensation pin. A resistor, capacitor combination connected to this
pin provides compensation for the control loop.
Feedback pin. The output voltage should be adjusted using a resistor
divider to provide 1.26V at this pin.
Analog ground pin.
Power ground pin.
Drive pin of the IC. The gate of the external MOSFET should be
connected to this pin.
Frequency adjust, synchronization, and Shutdown pin. A resistor
connected to this pin sets the oscillator frequency. An external clock
signal at this pin will synchronize the controller to the frequency of the
clock. A high level on this pin for
device will then draw less than 10µA from the supply.
Power supply input pin.
