Pin Function
Line (Input): 180Vdc maximum supply input. May be ?oated if unused.
Supply (Input): MIC9131 internal supply input.
Bias Resistor (External Component): Connect 562KΩ to ground.
Oscillator RC Network (External Components): Connect external resistor-ca-
pacitor network to set oscillator frequency.
Synchronization (Input): External oscillator input for slave operation of con-
troller. See OSC. Do not ?oat.
Compensation (External Components): Error ampli?er output for external
compensation network connection.
Feedback (Input): Error ampli?er inverting input.
Current Limit Selection (Input): When CPWR is high, an over-current condi-
tion at the ISNS input will terminate the gate drive and reset the soft-start
latch. If the CPWR pin is low, an over-current condition at the ISNS input
will terminate the gate drive signal, but will not cause a reset of the soft-start
circuit.
Reference (Output): Internal 5V supply. Will source 5mA maximum.
Enable (Input): Logic level enable/shutdown input; logic high = enabled (on),
logic low = shutdown (off).
Analog Ground (Return)
Soft-Start (External Components): Connect external capacitor to slowly ramp
up duty cycle during startup and over-current conditions.
Undervoltage Lockout (External Components): Connect to unbiased resistive
divider network to set controller ’s minimum operating voltage. Connect to
VBIAS if not needed.
Current Sense (Input): Connect between external switching MOSFET source
and switch current sense resistor.
Power Ground (Return)
Switch Drive Output (Output): Connect to gate of external switching MOS-
FET.
