Soft-Start
The output of the error amplifier starts from 0V and the inrush current is suppressed when starting by the CE
pin "H" input.
Moreover, the inrush current can be suppressed by gradually enlarging Duty of the PWM signal to the CE pin.
Selection of Inductors
The peak current of the inductor at normal mode can be calculated as next formula:
ILmax
=1.25 × ILED × VOUT / VIN + 0.5 × VIN × (VOUT - VIN) / (L × VOUT × fosc)
When the start-up or dimming control by CE pin, transient current flows, the peak current must be equal or
less than the current limit of the IC. The peak current should not beyond the rating current of the inductor.
When 4LEDs are driven with VIN
=3.6V, the recommended inductance value is 22μH or more.
Selection of Capacitors
Set 1
μF or more value bypass capacitor C1 between VIN pin and GND pin as close as possible.
Set 0.22
μF or more capacitor C2 between VOUT pin and GND pin.
As for R1201x05xA version, set 1
μF or more capacitor C2 between VOUT pin and GND pin.
