3 / 7 page TS2581 PWM Controller 3/7 Version: A11 Function Description Feedback Sense the regulated output voltage to complete the feedback loop, when VFB <0.4V, the SCP is happened. VSENSE The current limit sense pin, if VIN-VSENSE≧110mV, the over current is happened that it can turn-off driver cycle by cycle. OVP The Over Voltage sense pin, If VOVP >1.10V, the OVP is happened that it can turn-off the driver. You can set VOUT OVP voltage by outside resistances (R3 and R4), Please see below formula to set. ) 5 R 2 R + 1 ( × 10 . 1 = VOUT ) OVP ( The Over Voltage Protect, If VOVP >1.10V, the OVP is happened that it can turn-off the driver. Under Voltage Lockout (UVLO) To avoid error-operation of the device at low input voltages an under voltage lockout is included that disables the device, if the input voltage falls below 6.0V Thermal Consderation The SOP-8L package needs a heat sink under most conditions. The heat sink connect exposed pad of TS2581 to obtain best effect. The size of the heat sink depends on the input voltage, output voltage, output current and ambient temperature.
