Beschreibung
The IRS2982S is a versatile SMPS controller IC primarily intended for power supply and LED drivers in the 5 to 100 W power range suitable for buck, buck-boost and Flyback converters operating in Critical Conduction Mode (CrCM) and Discontinuous Conduction Mode (DCM) at light loads. Flyback converters will be covered in this application note, focusing on an isolated voltage-regulated design with Power Factor Correction (PFC). All of the control and protection required for the converter is integrated in the IRS2982S as well as a HV start-up cell to enable rapid start-up at switch-on over a wide line input voltage range. The IRS2982S is also able to provide PFC in a single-stage Flyback converter able to meet class D line current harmonic limits of the EN 61000-3-2 standard.
Eigenschaften
- Output Over-Voltage Protection (OVP) at VOUT less than or equal to 25 V
- Over-Current Protection (OCP) at 5.5 A
- Short-Circuit Protection (SCP)
- Brown-out protection, shut-down at 60 to 65 VRMS, start-up at 85 to 90 VRMS AC input voltages
Typische Anwendungen
- Power supply and LED drivers
