SMPS ICs for low-power systems
Figure 5 shows a typical curve for a reflected output voltage N
× V
o of 80 V. This voltage is
the output voltage Vo (see Figure 6) transferred to the primary side of the transformer with
the factor N (determined by the turns ratio of the transformer). Figure 5 shows that the
system switches exactly at minimum drain voltage for ringing frequencies of 480 kHz, thus
reducing the switch-on losses to a minimum. At 200 kHz, the next primary stroke is
started at 33
° before the valley. The switch-on losses are still reduced significantly.
8.5 Demagnetization
The system operates in discontinuous conduction mode all the time. As long as the
secondary stroke has not ended, the oscillator will not start a new primary stroke. During
the first tsuppr seconds, demagnetization recognition is suppressed. This suppression may
be necessary in applications where the transformer has a large leakage inductance and at
low output voltages.
8.6 Minimum and maximum duty factor
The minimum duty factor of the switched mode power supply is 0 %. The maximum duty
factor is set to 75 % (typical value at 100 kHz oscillation frequency).
8.7 OverCurrent Protection (OCP)
The cycle-by-cycle peak drain current limit circuit uses the external source resistor RI to
measure the current. The circuit is activated after the leading edge blanking time tleb. The
protection circuit limits the source voltage to Vsource(max), and thus limits the primary peak
current.
8.8 Short-circuit winding protection
The short-circuit winding protection circuit is also activated after the leading edge blanking
time. If the source voltage exceeds the short-circuit winding protection voltage Vswp, the IC
stops switching. Only a power-on reset will restart normal operation. The short-circuit
winding protection also protects in case of a secondary diode short circuit.
