(10) Regulation specifi cations describe the deviation as the line input voltage or output load current is varied from a

(12) Maximum PC board temperature is measured with the sensor in the center of the converter.
(13) Do not exceed maximum power specifi cations when adjusting the output trim.
Please observe the voltage input and output specifi cations in the Voltage Range Graph on page 7.
Output noise may be further reduced by adding an external fi lter. At zero output current, the output may contain
low frequency components which exceed the ripple specifi cation. The output may be operated indefi nitely with
no load. Due to the minimum duty cycle of the controller, operation below Vout=1.8V. with Vin at or above 12V.

All models are fully operational and meet published specifi cations, including “cold start” at –40˚ C.

output noise but may change the transient response. Newer ceramic caps with very low ESR may require lower
capacitor values to avoid instability. Thoroughly test your capacitors in the application. Please refer to the Output
Capacitive Load Application Note.
Otherwise, you risk having the converter turn off. The undervoltage shutdown is not latching and will attempt to
recover when the input is brought back into normal operating range.
overcurrent condition still exists, the restart current will be removed and then tried again. This short current pulse
prevents overheating and damaging the converter. Once the fault is removed, the converter immediately recovers
normal operation.
