XDPS21071 Forced Frequency Resonant Flyback controller Based on FW: REV 1.0 Product Highlights
• Integrated 600 V startup cell for fast startup and direct bus voltage sensing • Multi-mode operation with forced frequency resonant mode (FFR) • DCM operation guaranteed • Adaptive current limitation for variable Vout • Supports low no load input power to meet stringent regulatory standard • One pin UART interface for configuration
Features Description
• Multi-mode operation with BM, DCM The XDPS21071 is a digital PWM controller for high density • Configurable ZVS enabled line voltage adapter applications based on DCM flyback topology. A wide • ZVS gate drive signal for forced resonant mode feature set is provided in a DSO-12 package and requires • Built-in soft-start only a minimum of external components. An integrated • Built-in protection modes ASSP digital engine provides advanced algorithms for multi- • Brown-in and brownout detection via integrated HV mode operation and protection features. A forced frequency startup cell resonant operation support optimized high density adapter • Pb-free lead plating; RoHS compliant system dimensioning. In addition a one-time- • Halogen-free according to IEC61249-2-21 programmable (OTP) unit is integrated to provide a
Applications
selective set of configurable parameters, which can be • High density adapter/charger matched to a dedicated system design.
Product Validation
• Qualified for industrial applications according to the relevant tests of JEDEC47/20/22 85 ... 264 VAC
