Product details
Overview
98-0265PBF from Infineon Technologies is a dual-function PFC and electronic ballast controller IC for fluorescent lamp drivers, featuring 600 V high-voltage startup, 1.25 A gate drive capability, and integrated zero-crossing detection. It supports dimmable 2-lamp parallel operation in HID/fluorescent lighting systems with active PFC correction.
For engineers reviewing the 98-0265PBF datasheet, 98-0265PBF pinout, 98-0265PBF application, or 98-0265PBF equivalent, key selection criteria include HV startup voltage tolerance, lamp current regulation accuracy, PFC stage operating frequency range, and thermal shutdown threshold.
Technical Context
This controller integrates a continuous-conduction-mode (CCM) boost PFC pre-regulator controller and a half-bridge resonant ballast driver in a single 16-pin DIP package. It uses average-current-mode control for PFC and phase-shifted square-wave generation for lamp ignition and regulation.
The IC features internal 600 V startup circuitry, programmable PFC switching frequency up to 200 kHz, and dedicated lamp current sensing via external shunt resistor. Thermal protection triggers at 150 °C with automatic restart after cooldown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| PFC Mode | Continuous conduction mode (CCM) with average current sensing for >0.98 PF at full load |
| Startup Voltage | 600 V HV startup circuit enables direct AC line connection without auxiliary winding |
| Gate Drive Current | 1.25 A peak sink/source drives external half-bridge MOSFETs directly |
| Lamp Regulation | Programmable lamp current via external resistor; ±5% regulation accuracy over temperature |
| Thermal Shutdown | 150 °C junction temperature cutoff with hysteresis; auto-restart after cooling to 135 °C |
| Operating Frequency | PFC stage: 65–200 kHz; Ballast stage: 20–100 kHz, adjustable via external RC network |
Pinout & Package
16-pin plastic dual in-line package (DIP-16) with 0.3 inch body width and 0.1 inch pin pitch. Pin 1 marked by notch or dot; pins 1–8 on left side, 9–16 on right side when viewed top-down with notch facing left.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Supply voltage input | Internal LDO powers control logic; accepts 11–20 V DC after startup |
| CS | Current sense input | Connects to shunt resistor for lamp current feedback and overcurrent protection |
| ZCD | Zero-crossing detector input | Monitors AC line zero crossings for synchronized PFC timing and lamp ignition |
| HO | High-side gate driver output | Drives upper MOSFET of half-bridge; 1.25 A sink/source capability |
| LO | Low-side gate driver output | Drives lower MOSFET of half-bridge; complementary to HO with dead-time control |
| VSENSE | PFC voltage feedback | Inputs rectified PFC output voltage for regulation loop and OVP protection |
Key Features
| Feature | Design Value |
|---|---|
| Dual-stage integration | Single-chip solution replaces separate PFC controller + ballast driver, reducing BOM count by ≥7 components |
| 600 V HV startup | Eliminates need for auxiliary transformer or startup resistor network, simplifying primary-side design |
| Programmable lamp dimming | Supports analog dimming via external DC voltage on DIM pin (0–5 V = 100–10% lamp power) |
| Auto-restart protection | Lockout during overvoltage, overtemperature, or lamp fault; resumes after safe cooldown or reset |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PFC/ballast controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IR2159SPBF | Single-stage ballast-only controller; no integrated PFC; requires external PFC IC or passive solution | Limited to non-PFC-compliant installations; unsuitable for Class C harmonic requirements | Select only if PFC compliance is not mandated and cost minimization is primary goal |
| ICE2PCS01 | Standalone CCM PFC controller; no ballast functionality; requires separate half-bridge driver | Needs additional gate driver IC and lamp control logic; increases PCB area and component count | Choose when system architecture mandates modular PFC + ballast separation or higher PFC efficiency (>99%) is needed |
Compared with IR2159SPBF and ICE2PCS01, the 98-0265PBF provides integrated PFC+ballast functionality in one package, reducing design complexity and bill-of-materials while meeting strict harmonic standards-making it optimal for compact, compliant commercial lighting designs.

FAQ
What is the maximum lamp wattage supported by the 98-0265PBF?
The 98-0265PBF supports up to 2 × 58 W T8 lamps in parallel configuration, with total output power limited by external MOSFET ratings and heatsinking. At 230 VAC input, typical system efficiency exceeds 88%, delivering ~115 W total lamp power with <15 W controller losses.
Does the 98-0265PBF require an external microcontroller for dimming?
No. The 98-0265PBF implements analog dimming natively via its DIM pin, accepting a 0–5 V DC control signal to scale lamp current linearly from 10% to 100%. No firmware, communication interface, or external processor is required for basic dimming functionality.
Can the 98-0265PBF operate from 120 VAC mains without modification?
Yes. The IC supports universal input (90–305 VAC) through its programmable PFC reference and adaptive ballast frequency. For 120 VAC operation, the PFC output voltage must be set to ~170 VDC using the VSENSE divider, and the ballast frequency adjusted to maintain stable lamp ignition.
What protection features are built into the 98-0265PBF?
The 98-0265PBF includes overvoltage protection (OVP) on VSENSE, overcurrent protection (OCP) on CS, thermal shutdown at 150 °C, open-lamp detection, and short-circuit lockout. All protections trigger automatic restart after fault clearance and cooldown to 135 °C.
