Overview
The VIPERP3QR8STR is a high-voltage converter from the VIPerPlus family, integrating an 800 V avalanche-rugged power MOSFET with PWM current mode control. It supports flyback, buck, and buck-boost topologies. Key parameters include a switching frequency of 30 kHz ± 7% (Type X), 60 kHz ± 7% (Type L), or 120 kHz ± 7% (Type H). Input voltage range is 4.5 V to 30 V for VCC. No-load input power is less than 10 mW at 230 V AC. The device features embedded HV startup, sense-FET, error amplifier with 1.2 V reference, and protections including OCP, OLP, OVP, and thermal shutdown.

- Integrates an 800 V avalanche-rugged power MOSFET with PWM current mode controller
- Supports flyback, buck, and buck-boost converter designs
- Features jittered switching frequency to reduce EMI filter costs
- Includes embedded high-voltage startup and sense-FET
Applications
- Offline power supplies
- Industrial equipment
- Consumer appliances
Procurement Notes
Verify the specific suffix variant (X, L, or H) corresponding to the required switching frequency during procurement. Confirm package type availability matches design requirements. Ensure compatibility with eDesignSuite tools for accurate component selection and system development validation.
Selection Notes
Select based on required switching frequency options: 30 kHz, 60 kHz, or 120 kHz. Consider the integrated 800 V MOSFET for wide input voltage ranges. Evaluate the low no-load consumption for energy-saving standards compliance. Check protection feature requirements against application safety needs.
Part Context
Part of the VIPerPlus family, designed for high-efficiency offline power conversion. Combines high-voltage power section with advanced control logic in a single package. Targets applications requiring compact size and high reliability with minimal external components.
Replacement Considerations
Check datasheet for direct pin-compatible alternatives within the VIPerPlus series. Verify electrical parameter equivalence for MOSFET voltage rating and control loop characteristics before substitution.
