Current limiter operates by the following equation: 5. Vreft RNF Use non-polar type. Place as near the IC as possible. Oscillation frequency (fosc) is determined by the following equation: (1) When 300/360 selection is high level, fosc= . 2 ffe (Hz) (2) When 300/360 selection is low level, fosc= - fre (Hz) Use small leak current.
