TS4264G Preliminary 3-3 2004/01 rev. A Typical Application Circuit
Application Information
Dimensioning Information on External Components The input capacitor Cin is necessary for compensat ing line influences. Using a resistor of approx. 1 Ω in series with Cin, the oscillating of input inductivity and input capacitance can be clamped. The output capacit or Cout is necessary for the stability of the r egulating circuit. Stability is guaranteed at values Cout ≥10uF and an ESR ≤ 4 Ω within the operating temperature range. Circuit Description The control amplifier compares a reference voltage, which is kept highly precise by resistance adjustment, to a voltage that is proportional to the out put voltage and drives the base of the series transistor via a buffer. Saturation control, working as a function of load current, prevents any over-saturat ion of the power element. The IC is additionally protected against overload, over temperature and reverse polarity
