Battery powered wearables and fitness devices are typically very compact in size and have limited battery capacities.? These devices must use high efficiency power conversion to maximize user time between charging cycles.? For products with input power ports to connect battery charging devices, internal load circuit switching and power port protection are required.
Buck and Boost Converters
Set-top box and audio products AC/DC power supplies do not always provide specific voltage rails needed by application circuits. A voltage regulators?allow device main voltage rails to be stepped up or down at the point of load for specific application circuits.
For light load current requirements, a dual output linear regulator provide a compact low cost voltage regulation solution.
When high power conversion efficiency is desired, a DC/DC switching regulator can be a better choice. DC/DC switching regulators are available for voltage step-up and step-down applications.
The AS1602 is an integrated ESD and Common Mode EMI suppression IC used to improve EMC performance in Ethernet applications. It is built around Kinetic Technologies’ patented and proprietary Active EMC suppression technology to enable “Design for Compliance” approach to system design right from the start. This product helps eliminate EMC compliance challenges by providing consistent EMC performance and improvements utilizing silicon based technology as opposed to passive technologies. The AS1602 enables system designers to comply with:
CISPR22 and FCC Part 15, Class B requirements for Radiated and Conducted Emissions.
IEC 61000-4-3/6 requirements for Radiated and Conducted Immunity, Level 3 or higher.
High Efficiency, Wide Voltage Range 30-LED RGB Driver
Overvoltage and Surge Protection ICs
Set-top box and Audio products often need internal voltage rail on/off control to reduce standby or shutdown state power consumption or to enable/disable specific function circuits while the device is operating.
Integrated load switches provide simplified microcontroller I/O controlled power switching to eliminate the need for bias and level shift circuits associated with discrete MOSFET switches.
Load switches also provide slew rate limited turn on and shutdown mode reverse current blocking.
Set-top box and audio equipment use multicolor RGB LEDs for function indicator lamps. Indicator lamps show power on or signal connection conditions on devices that use LCD displays. For devices without displays, indicator lamps are needed to show power and all device function status.
RGB LED drivers allow simplified programmable control of LED color and brightness in an ultra small footprint package device.
Kinetic Technologies’ devices feature a wide range of ramp up/down timing for slow fade in/out effects and complex repeating patterns.
3-channel RGB LED drivers permit customer color control.
4-channel RGBW devices allow for driving a white LED in addition to the RGB LED.
Programming interface options include ExpressWire or I2C to ease integration with a wide variety of processors and operating systems.
