Diode D1
• Be sure to use Schottky-barrier diode as D1.
If other diodes like fast recovery diodes are used, ICs may be destroyed because of the reverse voltage generated by the recovery voltage or ON
voltage.
Choke coil L1
• If the winding resistance of the choke coil is too high, the efficiency may drop below the rated value.
• As the overcurrent protection starting current is about 3.5 A, take care concerning heat radiation from the choke coil caused by magnetic saturation
due to overload or short-circuited load.
Capacitors C1, C2, and C3
• As large ripple currents flow through C1 and C2, use high-frequency and low-impedance capacitors aiming for switching-mode-power-supply use.
Especially when the impedance of C2 is high, the switching waveform may become abnormal at low temperatures.
For C2, do not use a capacitor with an extremely low equivalent series resistance (ESR) such as an OS capacitor or a tantalum capacitor, which may
cause an abnormal oscillation.
• C3 is a capacitor for soft start. Leave pin 5 open if the soft start function is not used.
This pin is pulled up with a pull-up resistor inside the ICs.
To create the optimum operating conditions, place the components as close as possible to each other.
