High-efficiency, constant current LED driver with a wide dimming range and dual dimming via PWM and current amplitude.
**Features** ■ Compact and high efficiency By carefully selecting excellent passive components from the TDK Group and optimizing the circuit, we have implemented a design that minimizes noise while achieving high efficiency, resulting in a compact and efficient product. ■ On-board mounting type also available (ALD-605012P*131) With the lineup of DIP and SMD types, it has become possible to mount on the device's circuit board. As a result, the harness that was previously necessary for implementing board-type LED drivers in LCD panel LED backlights is no longer required. It can also be mounted using automatic assembly machines. ■ Achieves stable chromaticity, wide brightness adjustment range, and wide operating temperature range The ALD series employs PWM dimming and analog (current amplitude) dimming, achieving stable chromaticity and a wide brightness dimming range. Additionally, the high-efficiency design allows for use over a wide temperature range. ■ Adopts a highly versatile output connection method (ALD-605012P*131) It is possible to choose the output connection method according to the current capacity of the LED string.
