TDK ALD Series Constant Current LED Driver
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.

Applications/Examples of results
An AC-DC switching power supply essential for power conversion in electronic devices. A high-efficiency LED driver with a wide dimming range, ideal not only for backlighting LCD panels but also as a constant current power supply for LED equipment. Achieving high freedom and versatility in device design. By newly adding an on-board type to the traditionally popular ALD series, we have enabled diversification of mounting methods and reduction of required area. Additionally, the realization of a wide operating temperature range through increased efficiency, along with the adoption of flexible connection methods, has dramatically enhanced the freedom in our customers' device designs. The versatile ALD series will assist in the standardization of LED drivers.
