Datasheet, V2.0, 31 July 2003 PWM-QR IC TDA 16846/16846-2 TDA 16847/16847-2 Controller for Switch Mode Power Supplies Supporting Low Power Standby and Power Factor Power Management & Supply Neve r s t o p th in kin g .TDA 16846/TDA 16846-2/TDA 16847/TDA 16847 Revision History: Current Version: 2003-07-31 Previous Version Data Sheet TDA 16846: 2000-01-14 Previous Version Data Sheet TDA 16846-2: 2002-07-30 Page Page Subjects (major changes since last revision) (in previous (in current The data sheets for TDA 16846 and TDA 16846-2 have been Version) Version) combined in this version. Some measuring values are updated: 20 20 Pin 1 basic value 1 V and V slightly changed. 1B1 1B2 Pin 2 discharge current I changed from 0.5 mA to 0.6 mA. 2DC min Pin 14 overvoltage V threshold changed from 17.0 V to 17.1 V. 14OVmax 21 21 Pin 3 delay to switch on t slightly decreased. 3d Pin 4 charge current I and discharge current I added. 4ch 4DCH Pull high resistor R changed from 18kOhm to 15 kOhm according 1min to the data sheet for TDA 16846. 22 22 Pin 7 charge current I and upper threshold V small changed. 7 min 7Hmin 23 23 Pin 13 rise and fall time adapted according to C = 1nF (prev. 10 nF). 13 V slightly decreased (only TDA 16846-2, TDA 16847-2). 13aclow 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.
