Precautions for Use
1. External connection
(1) Wiring condition is very important. Noise associated with wiring inductance may cause problems.
For minimizing inductance, it is recommended to design the thick and short pattern (between large current diodos, input/output
capacitors, and terminal 1,2.) Single-point grounding (as indicated) should be used for best results.
(2) High switching speed and low forward voltage type schottky barrier diode should be recommended for the catch-diode D
because it affects the efficiency. Please select the diode which the current rating is at least 1.2 times greater than maximum
swiching current.
(3) The output ripple voltage is highly influenced by ESR(Equivalent Series Resistor)of output capacitor, and can be minimized by
selecting Low ESR capacitor.
(4) An inductor should not be operated beyond its maximum rated current so that it may not saturate.
(5) When voltage that is higher than V
IN
, is applied to V
OUT
, there is the case that the device is broken. Especially, in case
V
IN
is shorted to GND in normal condition, there is the case that the device is broken since the charged electric charge in
output capacitor (C
O
) flows into input side. In such case a schottly barrier diode or a silicon diode shall be recommended to
connect as the following circuit.
