AL1782

NOT RECOMMENDED FOR NEW DESIGN USE AL1783 AL1781/1782 SINGLE/DUAL DIMMABLE LINEAR LED DRIVER Description The DIODES™ AL1781/1782, a single/dual-channel dimmable Linear LED driver with PWM dimming control, is targeted for 1-Channel dimmable and 2-Channel tunable Smart Connected Lighting (SCL) applications. It serves as the LED driving element along with AC-DC Power Conversion Block and Intelligent wireless MCU as an emerging connected lighting applications. The AL1781/1782 key merits attribute to dimming performance, low standby power, ease of system implementation and great scalability. It supports High Frequency E-flicker free PWM dimming with Deep Dimming Capability: Support 40kHz down to 4%, 10kHz down to 1.0%, 4kHz down to 0.4%, or 1kHz down to 0.1% with good dimming linearity. When no PWM signal is detected by AL1781/1782, it will automatically enter the low-power mode for power saving purpose to be in compliance with Energy Star standby power requirement for connected lighting requirements. Integrates Adaptive Thermal Management (ATM) scheme to minimize non-productive power dissipation. The AL1781/1782 has protection features, including Under-VoltageLockout (UVLO), LED string Open/Short protection and Overtemperature protection (OTP). AL1781 is a single channel and AL1782 is a dual-channel LED driver. They can support high LED current (up to total 1500mA) applications and they are available in Low thermal resistance TSSOP-16EP (Type DX) package. Features  Input Volt...
