Sunnyvale, Calif.Maxim Integrated Products has introduced the MAX16822A/B and MAX16832A/C family of 2MHz, high-brightness (HB) LED drivers with an integrated MOSFET and high-side current-sense circuitry.
These highly integrated devices reduce the size, complexity, and cost of solid-state lighting (SSL) designs, simplifying the implementation of green lighting technology. Moreover, they provide the high conversion efficiency and advanced thermal-management capabilities critical to LED system designs.
The MAX16822A/B and MAX16832A/C are intended for MR16, MR111, and other architectural lighting applications, as well as front and rear automotive lighting (RCL, DRL, and fog/low-beam lights).
These high-voltage, switch-mode HB LED drivers are capable of delivering over 18W (MAX16822A/B) or 36W (MAX16832A/C) of output power with up to 95% efficiency, while driving as many as 15 white LEDs in series. The MAX16822A/B can deliver up to 350mA of continuous DC current, while the MAX16832A/C can deliver up to 700mA of continuous DC current to the LED string. These devices offer an analog dimming feature that allows the LED current to be controlled by an external DC voltage and PWM dimming input for a wide range of brightness levels.
Pricing: Starts at $0.99 for the MAX16822A/B, and $1.31 for the MAX16832A/C (1000-up, FOB USA).
Availability: Future product-contact factory for availability.
Datasheets: MAX16822A and MAX16832A.
