Power management and switching

Monolithic Power Systems

The EVM3695-20-PJ-00A evaluation board from Monolithic Power Systems demonstrates the capabilities of the MPM3695-20, a fully integrated, high-efficiency, synchronous step-down power module which provides an output current of up to 25 A. 

The MPM3695-20 adopts internally compensated constant-on-time control to provide fast transient response and to ease loop stabilization. The switching frequency can be set between 400 kHz and 1 MHz.

Microchip

The EV99F34A evaluation board from Microchip is based on its PD77718 power-over-Ethernet (PoE) manager and PD77010 PoE controller. 

 

Operating in controller mode using the PD77010, the EV99F34A board demonstrates eight IEEE 802.3bt 2-pair ports using the PD77718T3, and eight IEEE 802.3bt 4-pair ports using two PD77718T4 devices. The evaluation system provides designers with a suitable environment for evaluating the performance and implementation of these PoE managers and controller. The firmware supplied by Microchip supports both 4-pair and 2-pair operation. 

Key features: 

  • IEEE 802.3af/at/bt Type 4 standard compliant
  • Switch-domain USB-C® interface to be connected to a PC with Microchip GUI
  • PoE controller manual reset and disable ports
  • LED status indication for all ports 
  • Single power source 
  • Operating-temperature range: 0°C to 40°C
STMicroelectronics

The STEVAL-IFP035V1 board enables designers to evaluate circuit protection strategies for factory automation equipment using the STMicroelectronics CLT03 series digital input current limiters between sensors and processing units such as programmable logic controllers (PLCs).

STMicroelectronics

STEVAL-OET005 kits provides a hardware platform for evaluating the ECMF4-40A100N10 and other STMicroelectronics ESD protection or filtering devices for USB Type-C® connectors.

STMicroelectronics

The EVLVIPGAN100PD from STMicroelectronics is a 100 W USB Power Delivery (PD) 3.0 reference design for a USB Type-C® power adapter. 

It is an isolated power supply with a stand-alone USB PD controller. The evaluation board implements, at the primary side, a quasi-resonant flyback converter based on the ST VIPERGAN100, high-voltage flyback converter with optocoupler feedback for voltage regulation and a high-voltage gallium nitride (GaN) power switch. 

The converter combines a high-performance, low-voltage PWM controller chip with a 650 V start-up cell in a single package. The reference design achieves low standby power consumption thanks to the VIPERGAN100’s advanced power management and low quiescent current. 

To reduce the input mains current distortion, a power factor correction circuit based on the L6564 controller IC is used. At the secondary side, to increase system efficiency, rectification is based on the SRK1001 adaptive synchronous rectification controller.

The reference design also includes an STUSB4761 controller, which offers the benefits of a full hardware USB PD stack, allowing for robust, deterministic, and safe negotiation in line with USB PD standards.

STMicroelectronics

The STEVAL-A6983CV1 from STMicroelectronics is an evaluation board for testing the performance of the A6983C automotive-grade synchronous monolithic step-down regulators. The A6983C regulators are optimized for low power consumption in light-load mode.
