Описание:
When input power factor is necessary (like LED lighting, avionics or low THD application as well as the isolation), the single stage PFC Flyback is the best topology. The only drawback of such topology is the 100Hz/120Hz voltage ripple on output.

Возможности:

Power factor corrected (always > 0.95 at full load) Good efficiency (83% peak at 230Vac) Compact form factor EN61000-3-2 Class C compliant (LED lighting)

Описание:
This reference design is a complete charger module for evaluating a multi-cell synchronous notebook turbo boost charge using the bq24735 devices. It is designed to deliver up to 4 A of charge current to Li-ion or Li-polymer applications. The charge current is programmable by SMBus interface through the EV2300 interface board. The reference design does not include the EV2300 interface board. In order to evaluate the this solution, a user must order the EV2300 interface board separately.

Возможности:

# Series Cells: 1 to 4S Max Input Volts: 24V Max Charge Current: 8A Topology: Switch mode
