TDA7475A Overview
The TDA7475 is a new BCD OFF-LINE technology device intended for EL display lighting in carradio applications. Time-extended luminance is achieved by driving the display with constant-cur- BLOCK DIAGRAM rent pulses, which will automatically pensate for the ageing-related capacitance loss by providing more elevated voltage pulses.
