On-Bright Electronics OB6566
OB6566 is an active transition-mode (TM) power factor correction (PFC) controller for AC-DC switching mode power supply applications. With added system open loop protection feature, OB6566 shuts down system when the feedback loop is open. OB6566 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, Inductor short protection(ISP), and gate drive output clamping for external power MOSFET...| Part No. | OB6566 |
