Leadis Technology Launches New LED Driver Family

Leadis Technology, Inc. announced sample availability of the LDS8710, an innovative inductor-based, high-efficiency LED Driver that eliminates the expensive external Schottky diode normally used in the rectification loop. The LDS8710 is the first in a family of drivers which includes the LDS8716 and LDS8714. The LDS8710/16/14 drive up to 10, 6 and 4 LEDs in series, respectively, from a single-cell Lithium-Ion battery.

The LDS8710 family is ideal for applications such as smart phones, portable multimedia devices, personal navigation systems and digital photo frames where battery life, display size, resolution and brightness are critical.

Each device in the family features a patent-pending, integrated synchronous rectifier which eliminates the external Schottky diode and the need for complicated and costly isolation FETs. This reduces the bill of material and footprint of the display sub-system, and simplifies the design-in process and time to market of the end product.

“We are pleased to bring to the market the first LED Driver family featuring our patent-pending integrated synchronous rectifier. This novel architecture has been thought out with one main goal in mind: simplify our customers’ design experience and accelerate their time-to-market,” said Donato Montanari, vice president at Leadis. “By reducing the number of external components, allowing customers to pre-select maximum current ratings, implementing robust protection (over voltage, under voltage, over temperature and over current) and offering wide PWM dimming frequencies (100Hz to 10K Hz), every feature of the LDS8710 family is meant to improve our customer’s time-to-market and reduce their bill of material.”
