SY50133Z1 Datasheet (Silergy) - Flyback Regulator

SY50133Z1, Flyback Regulator

SY50133Z1 is a single stage Flyback regulator targeting at Constant Current/Constant Voltage (CC/CV) applications.

It integrates a 620V/4.4Ω MOSFET in a compact SO8 package to minimize the size.

Both the output current and voltage are sensed on the primary side, eliminating the opto-isolator and the
