This is a reference design for a SEPIC/linear LED-display backlight driver for eight parallel strings of 8 WLEDs (white LEDs) at 70mA/string. The dimming ratio is 4000:1. The input voltage is 16V to 36V with 50V transients. The design combines a SEPIC switching power supply with adaptive feedback and linear current sinks for high dimming ratios. The MAX16809 16-channel LED driver is featured.
Flyback converters are the preferred topology in isolated converters for medium and low power range applications due to their simplicity and economic considerations. As flyback converters are isolated converters, the output voltage and the current are traditionally regulated by utilizing the secondary side regulation (SSR) composed of an optocoupler and a secondary-error amplifier.
The TWR-K21F120MA is a development board for the NXP Kinetis K21 and K22 120 MHz 32-bit Arm ® Cortex ® -M4 MCUs with floating point unit.
The FRDM-KL05Z is an ultra-low-cost development platform enabled by the Kinetis L Series KL0x MCU family built on the Arm® Cortex®-M0+ processor.
Stackable monitors and protectors used in large lithium-ion batteries to provide monitoring, balancing and communication functions. Each bq76PL455A-Q1 EVM can manage 8 to 16 cells (12V minimum) in Li-ion battery applications. Up to 16 bq76PL455A-Q1 EVM modules can be stacked. The system provides fast cell balancing, diagnostic functions and modules for controller communication. An independent protection circuit is also integrated.
The bq297xy device provides protection for Li-ion/Li-polymer batteries and monitors across external power FETs to provide protection against high charge or discharge currents. Additionally, there is monitoring and protection against overcharging and depleted batteries. These features are achieved with very low current consumption when operating in normal mode.
42 W Dual Port Isolated Flyback Power Supply with 30 W USB PD 3.0 and 12 W USB-A Port Using InnoSwitch3-Pro with PowiGaN Technology (INN3379C-H302)
The MAX17681/MAX17681A is a high-voltage, highefficiency, iso-buck DC-DC converter designed to provide isolated power up to 5W. The device operates over a wide 4.5V to 42V input and uses primary-side feedback to regulate the output voltage .
Due to its simplicity and low cost, the flyback converter is the preferred choice for low-to-medium isolated DC-DC power-conversion applications. However, the use of an optocoupler or an auxiliary winding on the flyback transformer for voltage feedback across the isolation barrier increases the number of components and design complexity. The MAX17690 eliminates the need for an optocoupler or auxiliary transformer winding and achieves ±5% output voltage regulation over line, load, and temperature variations.
This design uses the MSP430F6736 device to implement a highly integrated single-chip energy metering (meter) solution. Hardware and software design files are provided to calculate various parameters of single-phase energy metering such as RMS current and voltage, active and reactive power and charge, power factor and frequency.
