*When a coil less value of 4.7

H is used at
FOSC=1.2MHz or when a coil less value of 1.5
μ
H is
used at FOSC=3.0MHz, peak coil current more easily
reach the current limit ILMI. In this case, it may
happen that the IC can not provide 600mA output
current.
NOTE ON USE (Continued)
14. In order to stabilize V
IN
’s voltage level and oscillation frequency, we recommend that a by-pass capacitor (C
IN
) be
connected as close as possible to the V
IN
& V
SS
pins.
15. High step-down ratio and very light load may lead an intermittent oscillation.
16. During PWM / PFM automatic switching mode, operating may become unstable at transition to continuous mode.
Please verify with actual parts.
17. Please note the inductance value of the coil. The IC may enter unstable operation if the combination of ambient
temperature, setting voltage, oscillation frequency, and L value are not adequate.
In the operation range close to the maximum duty cycle, The IC may happen to enter unstable output voltage operation
even if using the L values listed below.
<External Components>
18. It may happen to enter unstable operation when the IC operation mode goes into continuous operation mode under the
condition of small input-output voltage difference. Care must be taken with the actual design unit.
