No Connection
Slope Compensation Input. A resistor, R
amount of slope compensation with reference-voltage soft-start mode. Connecting this pin to
SGND enables duty-cycle soft-start with default slope compensation of 50mV/Fs. Setting V
4V enables reference voltage soft-start with default slope compensation of 50mV/Fs.
Switching Frequency Programming Resistor Connection. Connect resistor R
set the PWM switching frequency.
Frequency Dithering Programming or Synchronization Connection. For spread-spectrum frequency
operation, connect a capacitor from DITHER to SGND, and a resistor from DITHER to RT. To
synchronize the internal oscillator to the externally applied frequency (MAX17595/MAX17596 only),
connect DITHER/SYNC to the synchronization pulse.
Transconductance Amplifier Output. Connect the frequency compensation network between
COMP and SGND.
Transconductance Amplifier Inverting Input
Soft-Start Capacitor Pin for Flyback Regulator. Connect a capacitor C
the soft-start time interval.
Signal Ground. Connect SGND to the signal ground plane.
Current-Sense Input. Peak-current-limit trip voltage is 300mV (typ).
Power Ground. Connect PGND to the power ground plane.
