Circuit Description The individual functional sections of the device and their interactions are described below.

Power Supply at VS The device does not enable the output until the turn-ON threshold of VS is exceeded. The
duty factor active time/period can then rise from zero to the value set with K1 in the time determined by the soft start. The turn-OFF threshold lies below the turn-ON threshold. Below the turn-OFF threshold the output Q SIP is reliably low.

Frequency Generator The frequency is mainly determined by close-tolerance external components and the calibrated reference voltage.

The switching frequency at the output can be set by suitable choice of Rt and Ct.

The maximum possible duty factor can be reduced by a defined amount by means of a
resistor from CT to 0V GND. The maximum possible duty factor can be increased by a defined amount by means of a resistor from CT to VS.

Ramp Generator The ramp generator is controlled by the frequency generator and operates with the same
frequency. Capacitor Cr on the ramp generator is discharged by an internally-set current
and charged via a current set externally. The duration of the falling edge of the ramp generator output must be shorter than its rise time. Only then do the upper and lower switching levels of the ramp generator signal have their nominal values. In “voltage mode control” operation, the rising edge of the ramp generator signal is compared with an externally set dc voltage in comparator K1 for pulse-width control at
