This pin is the Error Amplifier output and is made available for loop
compensation
This is the inverting input of the Error Amplifier. It is normally
connected to the switching power supply output through a resistor
divider.
A voltage proportional to inductor current is connected to this input.
The PWM uses this information to terminate the output switch
conduction.
The Oscillator Frequency and maximum Output duty are programmed
by connecting resistor RT to Vref and capacitor CT to ground operation
to 500kHz is possible.
This pin is the combined control circuitry and power ground (8-pin
package only).
This output directly drives the gate of a power MOSFET.Peak current
up to 1.0A are soured and sunk by this pin.
This pin is the positive supply of the control IC.
This pin is the reference output . It provides charging current for
capacitor CT through resistor RT.
