- High isolation voltage
- Improved loading / line regulation
- Wide Input Voltage Range
- Point-of-Load Architecture
- Remote On/Off Control
Optional Protection Circuit
On/Off
Optional Protection 1:
Add a blocking diode to Vout
if current can flow backwards
into the output, as this can
damage the converter when it
+Vin
is powered down.
The diode can either be fitted
CTRL
across the device if the
source is low impedance or
fitted in series with the output
GND
(recommended).
