Notes:
1. An overtemperature protection circuit shuts down the converter if
the temperature at the output inductor exceeds 115°C. The unit will
restart automatically when the temperature at the output inductor
drops below 110°C.
2. For a 3.3V output, the input range is 4.0 to 5.5 VDC
3. No minimum load is required. Operation at no-load will not
damage these units.
4. These converters require no additional external components to
meet specifications. However, using external capacitors as shown
in the typical connection drawing at right may lower noise in some
applications.
5. Transient recovery is measured to within a 1% error band for a load
step change of 25% to 100%.
6. It is recommended that a fuse be used on the input of a power
supply for protection. Contact the factory for the correct rating.
1. C
1
and C
2 are Electrolytic capacitors. C2 should have a low ESR.
C3
is a ceramic capacitor.
2. When not being used, the Remote Sense pin (pin 3) should be
connected to VOUT as close to the converter as possible.
3. The output voltage of the SR50xxW may be trimmed down by
connecting an external resistor between the Trim Pin (pin 10) and
Ground (pins 5 & 6). This resistor value (in kΩ) is given by:
