Description
The L6564 is a current-mode PFC controller operating in transition mode (TM) and represents the compact version of L6563S as it embeds the same driver, reference and control stages in a very compact 10 pin SO package.
FEATUREs
■ Fast “bidirectional” input voltage feedforward (1/V2correction)
■ Accurate adjustable output overvoltage protection
■ Protection against feedback loop disconnection (latched shutdown)
■ Inductor saturation protection
■ AC brownout detection
■ Low (≤100 µA) start-up current
■ 6 mA max. operating bias current
■ 1% (@ TJ= 25 °C) internal reference voltage
■ -600/+800 mA totem pole gate driver with active pull-down during UVLO
■ SSOP10 package
APPLICATIONs
PFC pre-regulators for:
■ High-end AC-DC adapter/charger
■ Desktop PC, server, Web server
■ IEC61000-3-2 or JEITA-MITI compliant SMPS
