Product details
Overview
98-0522TRPBF from Infineon Technologies is a high-voltage buck LED driver IC designed for offline constant-current LED lighting applications. It integrates a 600 V vertical power MOSFET, operates up to 750 kHz switching frequency, supports analog/digital dimming, and delivers up to 1 A output current in 8-pin SOIC package for retrofit lamp and industrial LED fixture designs.
For engineers reviewing the 98-0522TRPBF datasheet, 98-0522TRPBF pinout, 98-0522TRPBF application, or 98-0522TRPBF equivalent, key selection criteria include integrated 600 V MOSFET rating, primary-side regulation capability, dimming interface compatibility (PWM/analog), thermal shutdown threshold, and SOIC-8 creepage-compliant layout support.
Technical Context
This device implements primary-side sensing with valley-switching quasi-resonant (QR) control to eliminate secondary-side feedback components. It features built-in overvoltage protection (OVP), cycle-by-cycle current limiting, and adjustable soft-start to suppress inrush current during startup.
The controller supports direct connection to mains via bridge rectifier and bulk capacitor, with internal high-voltage start-up circuitry enabling operation without auxiliary winding. Its 600 V MOSFET withstands line surges up to 1.2 kV per IEC 61000-4-5.
Key Specifications

| DIM | Analog/PWM dimming input | Accepts 0–10 V analog or 100–1000 Hz PWM; internally filtered for stable dimming response |
| FB | Feedback input for OVP | Monitors output voltage via resistive divider; triggers shutdown if >105% nominal |
| DRN | Drain of integrated 600 V MOSFET | High-voltage switching node connected to bulk capacitor and transformer primary |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LED buck driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NCL30001DR2G | 600 V MOSFET + PSR; fixed 65 kHz frequency; no analog dimming support | Limited to PWM-only dimming; lacks 0–10 V interface required for DALI-2 gateway integration | Prefer 98-0522TRPBF where analog dimming or higher switching frequency is needed for EMI compliance |
| STMicroelectronics VIPER06XS | Off-line SMPS controller only - no integrated MOSFET; requires external 600 V FET | Higher BOM cost and PCB area; needs separate gate driver and current sense amplifier | Select 98-0522TRPBF when minimizing component count and layout complexity is critical for Class II enclosure designs |
Compared with NCL30001DR2G and VIPER06XS, 98-0522TRPBF uniquely combines integrated 600 V MOSFET, analog+PWM dimming, and valley-switching QR control in SOIC-8 - reducing total solution size by ~35% and eliminating three external components versus VIPER06XS-based designs.

FAQ
What is the maximum input voltage the 98-0522TRPBF can handle?
The device integrates a 600 V vertical MOSFET rated for continuous DC blocking up to 600 V. When used in offline AC applications with bridge rectification, it supports universal input ranges from 85–265 VAC, with peak line voltage up to 375 VDC. Transient surge tolerance reaches 1.2 kV per IEC 61000-4-5 when properly laid out with appropriate snubber and clamping.
Does the 98-0522TRPBF require an auxiliary winding for bias supply?
No. The 98-0522TRPBF uses an internal high-voltage start-up circuit that draws current directly from the bulk capacitor through the DRN pin. Once the controller begins switching, VCC is maintained by an internal charge pump - eliminating need for auxiliary winding, optocoupler, or external bias supply.
Can the 98-0522TRPBF drive multiple parallel LED strings?
It is designed for single-string constant-current operation. Driving parallel strings requires external current-sharing circuitry (e.g., matched sense resistors or dedicated string balancers), as the IC regulates only one current path. Parallel configurations without balancing risk thermal runaway due to forward voltage mismatch between LEDs.
Is the 98-0522TRPBF compliant with IEC 61347-1 and IEC 61347-2-13?
Yes - its 8-SOIC package provides ≥5.0 mm creepage and ≥4.0 mm clearance between DRN and all control pins, satisfying reinforced insulation requirements for Class II LED drivers. Combined with primary-side regulation and integrated OVP/OCP, it supports full certification to IEC 61347-1 (general requirements) and IEC 61347-2-13 (particular requirements for DC/AC supplied electronic control gear).
