The NCP1253 is a highly integrated PWM controller capable of
delivering a rugged and high performance offline power supply in a
tiny TSOP−6 package. With a supply range up to 28 V, the controller
hosts a jittered 65 kHz or 100 kHz switching circuitry operated in peak
current mode control. When the power on the secondary side starts to
decrease, the controller automatically folds back its switching
frequency down to a minimum level of 26 kHz. As the power further
goes down, the part enters skip cycle while limiting the peak current.
To avoid sub harmonic oscillations in CCM operation, adjustable
slope compensation is available via the series inclusion of a simple
resistor in the current sense signal.
Besides the auto−recovery timer−based short−circuit protection, an
Over Voltage Protection on the VCC pin protects the whole circuitry in
case of optocoupler destruction or adverse open loop operation.
