Circuit Description
The TLE 4307 consists of 2 stages, the charge pump and the very low drop voltage
regulator.
Charge Pump
The power stage is used as a switching element, that is driven by a buffer. A current
source keeps the power stage on. When the output C of the charge pump reaches
V
C,off,
the power stage is switched off. It is active clamped, when the input I reaches
V
I,cl.
Optional, an external capacity can be connected between pin SL and I to limit the slew
rate at the input, when an inductive load drives the IC. Saturation control as a function of
the load current prevents any oversaturation of the power element. The regulator is
additionally protected against overload and overtemperature.
Very Low Drop Regulator
The control amplifier compares a reference voltage, made highly accurate by resistance
balancing, with a voltage proportional to the output voltage and drives the base of the
series PNP transistor via a buffer. Saturation control as a function of the load current
prevents any oversaturation of the power element. The regulator is additionally protected
against overload and overtemperature.
