The LM5070 HE (High Efficiency) evaluation board is designed to provide an IEEE802.3af compliant, Power over Ethernet (PoE) power supply.

The board is a 35 W, wide-range mains input, power factor corrected SMPS (switched mode power supply) suitable for all low power applications requiring a high PF (power factor), such as lighting applications and power supplies for LEDs. The low-cost L6562A and the simple flyback topology combine to provide a very competitive PFC controller solution.

The L4981 integrated circuit is a continous mode average current controller with several specific functions for active power factor correction. It can operate in high quality, medium/high power conversion range and provides all the necessary features to achieve a very high power factor, up to 0.99. Thanks to the BCD technology used, operative switching frequency higher than 200kHz can be used.

The Energy Monitoring PICtail™ Plus Daughter Board is a power monitor circuit that uses the highly integrated PIC18F87J72 single chip energy meter IC. This low-cost design does not use any transformers and requires few external components. It includes both an isolated USB connection for meter calibration and access to the device power calculation, and an isolated PICtail Plus connection for Explo…

This application note is a Ringing Choke Converter (RCC)-based, step-by-step cell phone battery charger design procedure.

The L6924D is a fully monolithic battery charger dedicated to single-cell Li-Ion/Polymer battery packs. It is the ideal solution for space-limited applications, like PDAs, handheld equipment, cellular phones, and digital cameras. It is designed with BCD6 technology and integrates all of the power elements (the Power MOSFET, reverse blocking diode and the sense resistor) in a small VFQFPN16 3mm x …

This document details the characteristics and performances of the PM8800 demonstration kit which has been designed to cover a broad range of power over Ethernet (PoE) applications. PM8800 is a highly integrated device embedding an IEEE802.3af compliant powered device (PD) interface together with a PWM controller and support for auxiliary sources.

The MCP7382X Li-Ion Battery Charger Evaluation Board features three circuits utilizing the MCP73826, MCP73827 and MCP73828 devices to demonstrate simple, stand-alone, linear charging of single cell Lithium-Ion/Lithium-Polymer battery packs (the battery packs are not included).

The UCC28063 is a dual-phase, transition-mode Power Factor Correction (PFC) pre-regulator. The UCC28063EVM-723 is an evaluation module (EVM) with a 390-V, 300-W, dc output that operates from a universal input of 85 VRMS to 265 VRMS and provides power-factor correction.
