SiP11203, SiP11204
Vishay Siliconix
Synchronous Rectifier Driver with Power Up/Down Control,
Output OVP, Error Amplifier and Precision Reference
DESCRIPTION
The SiP11203/SiP11204 provide the secondary side
error amplifier, reference voltage and synchronous
rectifier drivers for isolated converter topologies. Both
ICs are capable of being powered via conventional
bias supplies (output inductor winding or power
transformer winding), or from a pulse transformer
supplying the gate timing signals, and both parts
generate a regulated supply for powering the error
amplifier and control circuitry.
During power-up the SiP11203/SiP11204 ensure that
the synchronous rectifiers are held off until the supply
voltages are adequate to guarantee effective
operation of the driver circuits. During the soft-start
interval, a gradual ramp-up of the synchronous
rectifier conduction time is provided. Both ICs also
allow control of the discharge rate of the synchronous
rectifier driver outputs during power-down.
The SiP11203 and SiP11204 are available in a
Pb-free MLP44-16 package and are rated to handle
the industrial ambient temperature range of - 40 to 85 °C.
