Description
The AL9910/A high voltage PWM LED driver-controller provides an
efficient solution for offline high brightness LED lamps from rectified
line voltages ranging from 85V
external MOSFETs at switching frequencies up to 300kHz, with the
switching frequency determined by a single resistor. The AL9910
topology creates a constant current through the LEDs providing
constant light output. The output current is programmed by one
external resistor and is ultimately determined by the external
MOSFET chosen and therefore allows many low current LEDs to be
driven as well as a few high current LEDs.
The LED brightness can be varied by both Linear and PWM dimming
using the AL9910’s LD and PWM_D pins respectively. The PWM_D
input operates with duty ratio of 0-100% and frequency of up to
several kHz.
The AL9910 can withstand input voltages up to 500V which makes it
very resilient to transients at standard mains voltages. As well as
standard SO-8 package the AL9910 is available in the thermally
enhanced SO-8EP package.

... MOSFET Q1 is turned off. The stored energy in the inductor causes the current to continue to flow through the LEDs via diode D1. The AL9910’s LDO provides all power to the rest of the IC including Gate drive this removes the need for large high power start-up resistors. This means that operate correctly it requires around 0 ...

... When operating in buck mode the designer must keep in mind that the input voltage must be maintained higher than 2 times the forward voltage drop across the LEDs. This limitation is related to the output current instability that may develop when the AL9910 operates at a duty cycle greater than 0 ...

... The LED brightness can be dimmed either linearly (using the LD pin) or via pulse width modulation (using the PWM-D pin combination of both - depending on the application. Pulling the PWM_D pin to ground will turn off the AL9910. When disabled, the AL9910’s quiescent current is typically 0.5mA (0.65 for AL9910A). Reducing the LD voltage will reduce the LED current but it will not entirely turn off the external power transistor and hence the LED current – ...

... If power factor improvement is required then for the input power less than 25W, a simple passive power factor correction circuit can be added to the AL9910 typical application circuit. Figure 4 shows that passive PFC circuitry (3 current steering diodes and 2 identical capacitors) does not significantly affect the rest of the circuit. Simple passive PFC improves the line current harmonic distortion and achieves a power factor greater than 0 ...
