SP6562A Datasheet | SYNC POWER

DESCRIPTION SP6562A is an active transition-mode (TM) power factor correction (PFC) controller for AC-DC switching mode power supply applications. SP6562A features an internal start-up timer for standalone applications, a one quadrant multiplier with THD optimizer for near unity power factor, zero current detector (ZCD) to ensure TM operation, a current sensing parator with built-in leading-edge blanking, and a totem pole output ideally suited for driving a power MOSFET. APPLICATIONS - AC/DC Switching Power Adaptor - PC Power Supply - LCD TV Power Supply - Electronic Ballast SP6562A offers great protection coverage including system over-voltage protection (OVP) to eliminate runaway output voltage due to load removal, VCC under voltage lockout (UVLO), 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 , shuts down system when the feedback loop is open. FEATURES - Transition Mode (TM) Operation - Low Total Harmonic Distortion(THD) - Precise Adjustable Output Over-Voltage Protection - Open-Feedback Protection and Disable Function - Zero Current Detector - Internal Start up timer - Under-Voltage Lockout with 2.5V Hysteresis - Low Start-up (30µA) - Low (2.2m A) quiescent current - 1.4% internal reference voltage - -600/+800m A totem pole gate driver with active pull-down during UVLO and voltage clamp - SOP-8 Package PIN CONFIGURATION(SOP-8) PART MARKING 2020/07/07 Ver 2 Page 1 Power Factor Controller IC TYPICAL APPLCATION CIRCUIT FOR HIGH EFFICIENCY SMPS PIN DESCRIPTION Pin Symbol Description Inverting input of the error amplifier. The information on the output voltage of the PFC INV pre-regulator is fed into this pin through a resistor divider. The pin doubles as an ON/OFF control input. Output of the error amplifier. A pensation network is placed between this pin and INV to P achieve stability of the voltage...
