STR-S5707 Hybrid IC and its Applications in Switching Regulators | IC 4665

STR-S5707 (Hybrid IC for a Switching Regulator)

(1)General Description

The STR-S5707 is a Hybrid IC with a built in power transistor and a separate excitation control IC, designed for converter type switching mode power supply applications.

The IC is capable of quasi-resonant mode and requires small number of external component.

(2)Feature

•Small SIP isolated package : Resin sealed type (transfer mold)

•Lower power dissipation at a lighter load

•Many protection function : - Pulse-by-pulse over current protection

-Over-voltage protection with a latch

-Thermal protection with a latch

•These protection functions are incorporated and can be latched with an external signal.
