The MCP7383XEV-DIBC AC/USB Dual Input Battery Charger Evaluation Board demonstrates Microchip's stand-alone Linear Li-Ion Battery Charger. In this case the MCP73837 with Power-Good Monitor function. The MCP73837 require only minimum components to implement a complete battery charge management circuit.

The MCP7383XEV-DIBC AC/USB Dual Input Battery Charger Evaluation Board demonstrates Microchip's stand-alone Linear Li-Ion Battery Charger. In this case the MCP73838 with Timer Enable function. The MCP73838 require only minimum components to implement a complete battery charge management circuit.

The HPA107 evaluation module implements an IEEE 802.3af-compliant class-3 power interface and a non-isolated DC/DC switching converter using the Texas Instruments TPS23750 powered device (PD) controller in a typical power-over-Ethernet (PoE) configuration.

The board implements a 400 W, wide-range mains input, PFC pre-conditioner suitable for ATX PSU, Flat screen displays, etc. To make possible the use of a low-cost device like the L6562A at this power level, usually prohibitive for TM PFC, the chip operates with Fixed-Off-Time control.

The bqSWITCHER series are highly integrated Li-Ion and Li-Pol switch-mode charge management devices targeted at a wide range of portable applications. The bqSWITCHER series offer integrated synchronous PWM Controller and PowerFETs, high-accuracy current and voltage regulation, charge conditioning, charge status, and charge termination, in a small thermally enhanced QFN package. The system-control…

The MCP1630 Low-Cost Li-Ion Battery Charger is used to evaluate Microchip’s MCP1630 in a SEPIC power converter application. As provided, the MCP1630 Low-Cost Li-Ion Battery Charger is capable of charging a single-cell, Li-Ion battery pack from an input voltage of 6V to 18V.

The MCP73855 Battery Charger Evaluation Board is set up to evaluate simple, stand-alone, linear charging of single cell Li-Ion/Li-Polymer battery packs (the battery packs are not included). The board design provides constant current charging followed by constant voltage charging with automatic charge termination.

The MCP3905 Energy Meter Reference Design is a stand-alone low cost energy meter. It can act as either a stand alone energy meter, or as the analog front end design for LCD microcontroller based meters. The MCP3905 design is specified with an energy measurement error of 0.1% typical across 1:500 dynamic range for high accurate energy meter designs.

The LM5072 evaluation board is designed to provide a low cost, fully IEEE 802.3af compliant Power over Ethernet (PoE) power supply, capable of operating with both PoE and auxiliary (AUX) power sources.

Demonstration circuit 2043B is a lead-acid battery balancer featuring the LTC®3305. The LTC3305 balances up to four lead-acid batteries connected in series and incorporates all voltage monitoring, gate drive and fault detection circuitry.
