Technical Note
● Operating Guidelines
? PWM terminal
At Low the PFM mode skips the pulse of less than 7% On Duty. It is also switched over to the PWM mode if a certain
amount of load is reached or exceeded while in PFM mode. Moreover, it is switched to PFM mode if the load becomes
light. Please set the PWM terminal to High and use as the forced PWM mode if there is an influence of noise created by
modulation of the switching frequency.
? SCP Function
In case of circuit stoppage due to SCP, the protection is released by setting the UVLOSET voltage to L and the VBATT to
OFF.
? CH2 adding charge pump
Please set the Vo2 so that the VIN2A+VIN2B become not more than 15V because the voltage that is the sum of the VIN2A
voltage plus the VIN2B voltage is applied.
