The FRDM-HB2001FEVM evaluation kit allows users to practice using all features of the MC33HB2001 H-bridge device with FRDM-KL25z and SPIGen software.
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.
This reference design provides design guidance, data and other content for a 1.6kW 48V output power supply using semi-bridgeless PFC and isolated phase-shifted full-bridge DC-DC converters.
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.
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.
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.
The Multi-Standard 27W Mobile Charger enables the design of power supplies featuring extreme low standby power with the output voltage in full regulation, very high efficiency and high reliability. The NXP chipset used is targeting mobile and notebook power supplies with power requirements up to 100W. Supplies can be designed easily and with a minimum number of external components.
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)
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.
Power over Ethernet (PoE) is a technology that allows network cables to deliver power to a powered device (PD) through power-sourcing equipment (PSE) or midspan, and has many advantages over traditional methods of delivering power.
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 .
This 45W adapter reference board is designed to be a form, fit and functional test platform for low-cost charger applications to demonstrate the state-of-the-art 700V CoolMOS™ P7 Super Junction (SJ) MOSFETIPN70R600P7S in SOT-223 packaging. The reference adapter board is designed to fit into an extremely small form factor while featuring high efficiency, low standby power and various protection modes to achieve a highly reliable system. The board passes EMI (conducted and radiated), ESD immunity and surge testing and is ready for production after final verification by the customer with a small number of changes.

This design is a complete system for controlling a single extruder based 3-axis 3D printer. The system is managed by the MSP430F5529 LaunchPad and utilizes the DRV8846 for precision stepper motor control. The CSD18534Q5A is used as a low-side switch for warm bed heaters, extruder heaters, and cooling fans. The DRV5033 Hall sensor acts as a non-contact limit switch.
This reference design uses multiple microphones, a beamforming algorithm, and other processes to extract clear speech and audio amidst noise and other clutter. The rapid increase in applications that are used in noise-prone environments for voice activated digital assitants creates demand for systems that extract clear voice from noisy environments. The reference design uses a microphone array and a sophisticated signal processing to extract clear audio from noisy environments.
The NXP 15W multi-coil automotive transmitter solution is designed for in-vehicle wireless charging.
This EVK supports NXPMC33812. MC33812 is an engine control analog power IC suitable for motorcycle and single/double cylinder small engine control applications.
