Description
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 and Shutdown pin. A resistor connected to this
pin sets the oscillator frequency. A high level on this pin for
≥
30μs
will turn the device off. The device will then draw less than 10μA
from the supply.
Power Supply Input pin.
