Control circuit for a Self-Oscillating
Power Supply (SOPS)
Preliminary specification
TDA8385
FEATURES
• Bandgap reference generator
• Slow-start circuitry
• Low-loss peak current sensing
• Over-voltage protection
• Hysteresis controlled stand-by
function
• Error amplifier with gain setting
• Programmable transfer character
generator
• Protection against open- and
short-circuited feedback loop
• Over-load current fold back
characteristic
• LED driver
• Demagnetization protection
• Programmable determination of
switch-on moment of switching
transistor for low-switching losses
• Feed-forward input
• Regulation-indicator output
• Programmable minimum on-time of
switching transistor
• Accurate peak-current setting.
GENERAL DESCRIPTION
The TDA8385 is intended to be used
in combination with the opto-coupler
(CNR50) as a control unit for a
self-oscillating power supply.
