OB6563
High Performance PFC Controller
Product Specification
GENERAL DESCRIPTION
OB6563 is an active transition-mode (TM) power
factor correction (PFC) controller for AC-DC
switching mode power supply applications.
OB6563 features an internal start-up timer for
stand-alone applications, a one quadrant
multiplier with THD optimizer for near unity power
factor, zero current detector (ZCD) to ensure TM
operation, a current sensing comparator with built-
in leading-edge blanking, and a totem pole output
ideally suited for driving a power MOSFET.
OB6563 offers great protection coverage including
system over-voltage protection (OVP) to eliminate
runaway output voltage due to load removal, VCC
under voltage lockout (UVLO), cycle-by-cycle
current limiting, multiplier output clamping that
limit maximum peak switch current, and gate drive
output clamping for external power MOSFET
protection.
With added system open loop protection feature,
OB6563 shuts down system when the feedback
loop is open.
In OB6563, the dynamic OVP sensing current is
set to 10uA, which will decrease system standby
power greatly. When used with On-Bright PWM
controller OB2298 or Quasi-Resonant controller
OB2203 in a 150W AC/DC power design, it can
deliver <0.4W standby power at universal AC
range input.
OB6563 is offered in SOP-8 and DIP-8 packages.
