TDA 16846-2/TDA 16847-2:

Improvements of TDA 16846-2/TDA16847-2 compared with TDA 16846/TDA16847

Pin 5

OCI

Expanded input voltage range down to zero, series resistor between

pin 5 and ground is no longer necessary.

Pin 7

SYN

Improved startup to prevent the transformer from saturation also in

fixed frequency and synchronized mode.

Pin 11

PVC

Noise-immunity improved by spike blanking.

Pin 13

OUT

Reduced output voltage level for off state.

Pin 14

VCC

Noise-immunity improved by spike blanking.
