The LM3643 is a dual LED flash driver that provides a high level of adjustability within a small solution size. The LM3643 utilizes a 2-MHz or 4-MHz fixed-frequency synchronous boost converter to provide power to the dual 1.5-A constant current LED sources. The total LED current the LM3643 boost can deliver is 1.5 A (ILED1 + ILED2 ). Read more...More Product Announcements from Texas Instruments
Skyworks introduces a step-up, three-channel LED driver with an I2C interface and pulse width modulation dimming control, offering 10-bit dimming accuracy down to 0%. The SKY82896 features a wide input voltage range of 2.5 V to 5.5 V and high-boost switching frequency. Minimal external components reduce the solution size and make the device suitable for LED backlighting in sin... Read more...More Product Announcements from Skyworks Solutions, Inc.
