TECHNICAL NOTES
When you use these ICs, consider the following issues:
Set external components such as an inductor, C
IN
, COUT as close as possible to the IC, in particular, minimize
the wiring to VIN pin and PGND pin. Reinforce the VIN, PGND, and VOUT lines sufficiently. Large switching
current may flow in these lines. If the impedance of VIN and PGND lines is too large, the internal voltage level in
this IC may shift caused by the switching current, and the operation might be unstable. The wiring between
VOUT and load and between L and VOUT should be separated.
The recommended capacitance value for the CIN capacitor connected between the V
IN
and PGND pins is
2.2F or more. Also, the recommended capacitance value for the COUT capacitor is 4.7F ~ 10F.Please be
aware of the characteristics of bias dependence and temperature fluctuation of ceramic capacitor.
Choose an inductor with inductance range from 2.2μH to 4.7μH. The phase compensation has been made by
these values with output capacitors. The recommendation characteristics of the inductor are low DC resistance,
large enough permissible current, and strong against the magnetic saturation. Inductance value may shift
depending on an inductor. If the inductance value at an actual load current is low, LX peak current may increase
and may overlap the LX current limit. As a result, over current protection may work.
Over current protection circuit, Latch-type protection circuit may be affected by self-heating and heat radiation
environment.
The performance of power supply circuits using this IC largely depends on the peripheral circuits. Please be
very careful when setting the peripheral parts. When designing the peripheral circuits of each part, PCB
patterns, and this IC, please do not exceed the rated values (Voltage, Current, Power).
