hysteresis is required on power good comparator before
signal going high again.
Soft ? Start
A soft start limits inrush current when the converter is
enabled. After a minimum 300 m s delay time following the
enable signal, the output voltage starts to ramp up in 100 m s
(for external adjustable voltage devices) or with a typical
10 V/ms slew rate (for fixed voltage devices).
Active Output Discharge
An output discharge operation is active in when EN is low.
A discharge resistor (500 W typical) is enabled in this
condition to discharge the output capacitor through SW pin.
Cycle ? by ? Cycle Current Limitation
The NCP6334B/C protects the device from over current
with a fixed ? value cycle ? by ? cycle current limitation. The
typical peak current limit ILMT is 2.8 A. If inductor current
exceeds the current limit threshold, the P ? MOSFET will be
turned off cycle ? by ? cycle. The maximum output current
can be calculated by
(eq. 1)
2 @ V IN @ f SW @ L
where VIN is input supply voltage, VOUT is output voltage,
L is inductance of the filter inductor, and f SW is 3 MHz
normal switching frequency.
Thermal Shutdown
The NCP6334B/C has a thermal shutdown protection to
protect the device from overheating when the die
temperature exceeds 150 ° C. After the thermal protection is
triggered, the fault state can be ended by re ? applying VIN
and/or EN when the temperature drops down below 125 ° C.
