STEVAL-ISA102V2

The STEVAL-ISA102V2 from STMicroelectronics is a 80W high performance transition mode PFC evaluation board based on L6562A. The L6562A is a current-mode PFC controller operating in transition mode (TM). With the same pin-out as its L6562 predecessor, the L6562A offers improved performance mainly in terms of efficiency and noise immunity. The STEVAL-ISA102V2 implements an 80W, wide-range mains input and a PFC pre-conditioner suitable for lighting, adapters and consumer SMPS, etc.
