UNIVERSAL HIGH VOLTAGE HIGH BRIGHTNESS LED DRIVER
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
AC
up to 277V
AC
. The AL9910 drives
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.

Notes: 4. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional
operation of the device at these or any other conditions above those listed in the operational sections of this specification is not implied. Exposure
to absolute maximum rating conditions for extended periods may affect device reliability.
All voltages are with respect to Ground. Currents are positive into, negative out of the specified terminal.
5. Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken when
handling and transporting these devices

Notes: 6. Maximum ambient temperature range is limited by allowable power dissipation. The Exposed pad SO-8EP with its lower thermal impedance allows
the variants using this package to extend the allowable maximum ambient temperature range.
7. When using the AL9910 in isolated LED lamps an auxiliary winding might be used.
