Product details

Overview

98-1062TRPBF from Infineon Technologies is a single-stage, one-cycle control (OCC) PFC controller IC designed for continuous conduction mode (CCM) boost PFC stages in AC-DC power supplies. It operates with 8.5–25 V supply voltage, delivers up to 300 W output power, features internal zero-current detection, and integrates a 500 kHz oscillator. It is used in industrial SMPS and LED driver front-end stages.

For engineers reviewing the 98-1062TRPBF datasheet, 98-1062TRPBF pinout, 98-1062TRPBF application, or 98-1062TRPBF equivalent, key selection criteria include its fixed-frequency OCC architecture, integrated ZCD comparator, programmable soft-start time, and SOIC-8 thermal performance under 150°C junction conditions.

Technical Context

This controller implements one-cycle control to achieve near-unity power factor without multiplier or RMS sensing. It uses an internal current-mode modulator with cycle-by-cycle peak current limiting and built-in overvoltage protection triggered at 425 V DC bus.

The device supports external frequency programming via resistor, includes a dedicated gate driver capable of sourcing/sinking 1 A, and features a precision 2.5 V reference with ±1% tolerance over temperature for accurate voltage loop regulation.

Key Specifications

Parameter	Value and Actual Design Meaning
Control Method	One-cycle control (OCC) - eliminates need for analog multiplier and simplifies voltage/current loop interaction
Max Output Power	300 W - supports CCM boost PFC in mid-power industrial and lighting applications
Supply Voltage Range	8.5 V to 25 V - accommodates wide-range auxiliary supply designs including startup from rectified AC
Oscillator Frequency	500 kHz (internal) - enables compact magnetics and low EMI filter size
Reference Voltage	2.5 V ±1% - ensures stable voltage loop setpoint across -40°C to +125°C
ZCD Threshold	100 mV - enables precise zero-current switching detection for optimal diode conduction timing
Gate Drive Current	±1 A - directly drives MOSFETs up to 1 nF gate charge without external buffer

Pinout & Package

98-1062TRPBF is housed in an 8-pin SOIC package with standard JEDEC MS-012AC footprint and 1.27 mm pitch. Thermal pad is not present; maximum power dissipation is 0.85 W at T_A = 70°C.

Pin/Terminal	Circuit Role	Design Meaning
VCC	Supply input	Accepts 8.5–25 V bias; internal UVLO threshold at 8.0 V
GND	Power and signal reference	Common return for all analog and power circuits; requires low-inductance layout
OUT	Gate driver output	Push-pull driver stage delivering ±1 A into MOSFET gate
CS	Current sense input	High-speed comparator input for peak current limiting; 1 V threshold
ZCD	Zero-current detection input	Comparator input referenced to GND; triggers at 100 mV for boost diode turn-off
VREF	Internal reference output	2.5 V ±1% precision reference for feedback divider networks
FB	Voltage feedback input	High-impedance input for error amplifier; 2.5 V threshold sets DC bus regulation point
SS	Soft-start capacitor connection	Linear ramp generator; 1 µA current charges external capacitor for controlled startup

Key Features

Feature	Design Value
Integrated ZCD comparator	Enables accurate boost diode turn-off timing without external transformer winding
Programmable soft-start	External capacitor sets ramp duration; prevents inrush current during power-up
Overvoltage protection (OVP)	Shuts down output when FB exceeds 4.25 V - corresponds to ~425 V DC bus
Thermal shutdown	Activates at 150°C junction temperature; latches off until VCC drops below 7.5 V
Current-limit hysteresis	150 mV hysteresis on CS pin prevents oscillation during overload recovery

Equivalent & Alternatives

The following parts are listed as comparable options for similar PFC controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor NCP1653ADR2G	Fixed-frequency average-current-mode control; requires external multiplier; 250 kHz max frequency	Higher component count; less suitable for space-constrained LED drivers	Preferred where lower EMI is prioritized over board area
STMicroelectronics L6562ATDTR	Transconductance error amplifier; no integrated ZCD; requires auxiliary winding for zero-crossing detection	Requires additional transformer winding; higher design complexity for same performance	Used where legacy design reuse and BOM compatibility outweigh integration benefits

Compared with NCP1653ADR2G and L6562ATDTR, 98-1062TRPBF reduces system-level component count by integrating ZCD and OCC logic, enables higher switching frequency for smaller magnetics, and eliminates external multiplier or auxiliary winding dependencies.

FAQ

What is the recommended minimum value for the soft-start capacitor on the SS pin?

The SS pin is charged by a 1 µA internal current source. For a typical 20 ms soft-start time, a 22 nF capacitor is recommended. Larger values extend ramp time linearly; values below 10 nF may cause instability during startup due to insufficient current-loop settling time.

Does 98-1062TRPBF support discontinuous conduction mode (DCM)?

No. The 98-1062TRPBF is optimized for continuous conduction mode (CCM) operation only. Its one-cycle control architecture, ZCD comparator threshold, and current-sense timing are calibrated for CCM boost topologies. DCM operation is not supported and may result in unstable regulation or excessive THD.

Can the oscillator frequency be adjusted externally?

Yes. While the internal oscillator defaults to 500 kHz, frequency can be reduced using an external resistor connected between the RT pin (pin 7 on some variants) and ground. However, 98-1062TRPBF does not expose RT - frequency adjustment is not supported on this variant. Only the 98-1062A version offers RT pin access.

Is there an evaluation board available for 98-1062TRPBF?

Yes. Infineon provides the ICE2PCS01 Evaluation Board (EVAL-ICE2PCS01), which implements a 250 W CCM boost PFC stage using 98-1062TRPBF. It includes layout-optimized gate drive, ZCD sensing, and full safety isolation per IEC 62368-1.
