Description

The AL3022 is a constant 150KHz, voltage mode, external compensation boost controller. The AL3022 has low reference voltage and makes it ideal for low cost LED backlight supplies. 
 
The AL3022 can support external PWM dimming and analog dimming. The AL3022 employs complete protection to ensure system security. The device integrates Under Voltage Lockout, Over Voltage Protection, Over Current Protection, Output Voltage (VOUT) Short to GND Protection and Over Temperature Protection to protect the circuit.
 
 
To satisfy the requirements for small mounting space constraints, this IC is available in SO-8 package to save space.

Application(s)

  • LED TV
  • LED Monitor
  • LED Display Module
