Internally regulated supply voltage. 10V nominal for AL9910A. Can supply up to 1 mA
for external circuitry. A sufficient storage capacitor is used to provide storage when
the rectified AC input is near the zero crossings
Linear Dimming by changing the current limit threshold at current sense comparator
Oscillator control. A resistor connected between this pin and ground sets the PWM
frequency.
Exposed Pad (bottom). Connect to GND directly underneath the package.

Dimming Description
From the schematic circuit, U2A, R25, R29, R13, R21, R8, R12, R14, R15, C7, U2B,
R25, R29, R20, C12, C11, R40, R3, R40 and R41 belong to a dimmer detector. The
dimming circuit is functioning by comparing integral and differential portion of the
voltage after the D3 & D5 diodes. R13, R21, R12 and C8 components are an integrator
circuit with ~20ms integration time. R14, R15 and C10 components are a differentiator
circuit with ~34us time constant. Voltage after differentiation through voltage divider
(R14, R15) and D8 changing capacitor C7 charge. U2A compares integral and
differential portions of AC input voltage. All voltage dividers above maintain a voltage
such that if there is no triac dimmer present, then the voltage at pin #2 on U2A is
greater than the voltage at pin #3. If a dimmer is present, then differential portion will be
much higher. At any dimmer position, the differential will be greater than integral
portion. Therefore, on the U2A output voltage is LOW if there is no dimmer and HIGH if
there is a dimmer present. If there is a dimmer present, then a high voltage from the
U2A output makes Q2 conductive and switching ON current sink (Q2). This current sink
has a double functionality:
1) When dimmer’s triac is conducting, it adds current necessary to keep triac
conducting. Value of this current depends on R17 and Q2 V GS voltage.
2) When dimmer’s triac is OFF, Q2 is quickly discharging dimmer’s capacitors. R28
makes it more stable and R47 is limiting U2A output current.
Schematic portion responsible for shutting down driver at a very low dimmer settings
(low end) is assembled on U2B, R25, R29, R20, C12, C11, R40, R3, R40 and R41,
which will prevent LED flickering.
Power factor correction circuit contains Q6, R43, R44 and R42. It is working as a
controllable voltage divider (R9, Q6, R43, R44) in the current feedback loop. A voltage
on C5 is a control voltage for Q6. It allows to bring input current shape close to the
voltage shape and increase the power factor. R42 is used to limit current feedback in
case of increased input AC voltage and reducing LED current from AC voltage changes.
