Siemens Power Hybrid for SMPS
Preliminary Data
SPH 4692
Bipolar IC
Features
q Fold-back characteristics provides overload protection for
external components
q Burst operation under secondary short-circuit condition
implemented
q Protection against open or a short of the control loop
q Switch-off if line voltage is too low (undervoltage switch-off)
q Line voltage depending compensation of fold-back point
q Soft-start for quiet start-up without noise generated by the
transformer
q Chip-over temperature protection implemented (thermal
shutdown)
q On-chip ringing suppression circuit against parasitic
oscillations of the transformer
Power MOSFET
q VDS = 600 V
q R DS ON = 3.0 Ω
q Repetitive Avalanche
P-DIP-18-4
Type
SPH 4692
Ordering Code
Q67000–A5069
Package
P-DIP-18-4
The Siemens Power Hybrid SPH 4692 contains the SMPS IC TDA 4605-3 as well as the SIEMENS
POWER MOSFET in a P-DIP-18 package.
The IC TDA 4605-3 controls the MOS-power transistor and performs all necessary control and
protection functions in free running flyback converters. Because of the fact that a wide load range
is achieved, this IC is applicable for consumer as well as industrial power supplies.
