Product details

Overview

ICE2PCS03GHUMA1 from Infineon Technologies is an 8-pin standalone Power Factor Correction (PFC) controller IC for boost-topology converters operating in Continuous Conduction Mode (CCM) with average current control. It features a trimmed internal fixed switching frequency of 100 kHz ±5%, 3 V ±2% internal reference voltage, input brown-out protection (VINS turn-on at 1.5 V, shutdown at 0.71 V), and gate drive output capable of 1.5 A source / 2.0 A sink. It is used in universal-input (85–265 VAC) AC-DC front-end power supplies for LED drivers, industrial SMPS, and Class D-compliant consumer electronics.

For engineers reviewing the ICE2PCS03GHUMA1 datasheet, ICE2PCS03GHUMA1 pinout, ICE2PCS03GHUMA1 application, or ICE2PCS03GHUMA1 equivalent, key selection considerations include its CCM average-current control architecture, external voltage/current loop compensation flexibility, brown-out hysteresis behavior, soft-start timing profile, and compatibility with auxiliary-supplied VCC (11–26 V).

Technical Context

The ICE2PCS03GHUMA1 implements a cascaded dual-loop control system: an inner current loop regulates sinusoidal input current via ISENSE feedback and ICOMP compensation, while the outer voltage loop stabilizes VOUT using VSENSE feedback and VCOMP compensation. Both loops are fully externally compensated for design adaptability.

It integrates cycle-by-cycle peak current limiting, soft overcurrent protection, open-loop detection, output over-voltage protection, and VCC under-voltage lockout (11.8 V turn-on, 11 V turn-off). The GATE driver delivers rail-to-rail switching with internal 15 V clamp and supports fast load-step response in high-power PFC stages.

Key Specifications

Parameter	Value and Actual Design Meaning
Switching Frequency	100 kHz ±5% at 25°C - fixed internal oscillator enables predictable EMI filter design and thermal management.
Input Voltage Range	85–265 VAC - supports universal mains operation without manual range switching.
Internal Reference	3.0 V ±2% - ensures precise VSENSE regulation threshold and consistent OVP/OLP trip points.
Brown-Out Threshold	VINS turn-on: >1.5 V; shutdown: <0.71 V - provides hysteresis to prevent chattering during marginal line conditions.
GATE Drive Strength	1.5 A source / 2.0 A sink - directly drives medium-power MOSFETs (e.g., 600 V CoolMOS™) without external buffers.
VCC Operating Range	11–26 V - compatible with standard auxiliary flyback or capacitive-dropper supplies.
Max Duty Cycle	95% (typ) - enables high step-up ratio in boost converters with low-line input.

Pinout & Package

ICE2PCS03GHUMA1 is housed in a PG-DSO-8 (SOIC-8) surface-mount package with standard 1.27 mm pitch and exposed pad for thermal enhancement.

Pin/Terminal	Circuit Role	Design Meaning
1 GND	IC Ground Reference	Primary return path for all internal analog and power circuits; must be low-impedance connection to PCB ground plane.
2 ICOMP	Current Loop Compensation Node	Connects external RC network to stabilize inner current control loop; sets bandwidth and phase margin for ISENSE feedback.
3 ISENSE	Current Sense Input	Accepts voltage drop across external shunt resistor (R_SENSE) to regulate average inductor current; also feeds peak current limit comparator.
4 VINS	Brown-Out Sense Input	Monitors scaled rectified AC line via resistive divider; triggers shutdown when input falls below 0.71 V (≈85 VAC).
5 VCOMP	Voltage Loop Compensation Node	Output of OTA1 error amplifier; connects external compensation network to set outer loop stability and transient response.
6 VSENSE	VOUT Feedback Input	Receives scaled output bus voltage; compares against 3 V internal reference to regulate DC bus within ±1%.
7 VCC	Power Supply Input	Accepts 11–26 V auxiliary supply; includes UVLO with 11.8 V turn-on and 11 V turn-off thresholds.
8 GATE	High-Current Gate Driver Output	Drives external MOSFET gate with 1.5 A source / 2.0 A sink; clamped at 15 V to protect gate oxide.

Key Features

Feature	Design Value
Average Current Control Architecture	Enables sinusoidal input current draw meeting IEC 61000-3-2 Class D harmonic limits without complex digital control.
External Loop Compensation	Independent ICOMP and VCOMP pins allow full customization of current/voltage loop dynamics for varied choke and capacitor selections.
Direct Brown-Out Sensing with Hysteresis	VINS pin eliminates need for external comparators or microcontroller intervention during low-line events.
Fast Dynamic Load Response	Enhanced voltage loop response reduces output bus droop during sudden load steps in high-power LED or motor drives.
Integrated Protection Suite	Combines IBOP, SOC, PCL, OLP, OVP, and UVLO to eliminate discrete protection components and reduce BOM count.

Consumer Audio Amplifiers

Medical Equipment SMPS

Use Scenario: High-fidelity Class D audio amplifiers requiring low-noise, regulated DC rails and minimal harmonic injection into shared building wiring.

IC Role / Device Role / Timing Role: Active PFC controller in dual-stage AC-DC conversion, preceding isolated DC-DC stage.

Use Value: Reduces THD of input current to <8% at full load, preventing interference with sensitive analog audio circuitry.

Use Scenario: Auxiliary power supply for diagnostic imaging equipment where uninterrupted operation and safety-critical reliability are mandated.

IC Role / Device Role / Timing Role: Regulated PFC controller ensuring stable DC bus despite variable hospital mains quality and backup generator transitions.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ICE2PCS02G	No integrated brown-out detection; requires external circuitry for VINS functionality.	Suitable only where brown-out immunity is not required or implemented externally.	Select ICE2PCS02G only if cost sensitivity outweighs need for integrated brown-out protection and board space is unconstrained.
UCC28070	Interleaved dual-channel CCM controller; higher pin count (20-pin TSSOP); no internal 100 kHz oscillator (requires external clock or sync).	Targeted at >500 W systems requiring interleaving for reduced ripple and EMI.	Choose UCC28070 when scaling beyond 300 W or needing interleaved topology; ICE2PCS03GHUMA1 remains optimal for single-phase ≤300 W designs.

Compared with ICE2PCS02G, ICE2PCS03GHUMA1 adds integrated brown-out hysteresis and simplifies layout; versus UCC28070, it trades channel count and flexibility for lower component count and smaller footprint in single-phase applications.

FAQ

What is the recommended VCC auxiliary supply configuration for ICE2PCS03GHUMA1?

An auxiliary flyback converter or capacitive-dropper supply delivering 12–15 V at ≥20 mA is recommended. VCC must exceed 11.8 V to enable operation and remain above 11 V during transients. A 100 µF low-ESR electrolytic capacitor should be placed close to the VCC pin to suppress ripple and ensure stable UVLO behavior during load jumps.

How does the ICE2PCS03GHUMA1 implement brown-out protection without external comparators?

The VINS pin internally compares the scaled AC line voltage against two precision thresholds: 1.5 V for turn-on and 0.71 V for shutdown. This built-in hysteresis eliminates external components while providing noise-immune detection of sustained low-line conditions below 85 VAC, triggering automatic standby mode without latch-up.

Can ICE2PCS03GHUMA1 operate in discontinuous conduction mode (DCM)?

Yes - it operates primarily in CCM but transitions to DCM under light-load conditions depending on boost inductor value and output power. The average-current control loop remains functional in DCM, and the device continues to meet IEC 61000-3-2 Class D requirements even in this mode due to inherent harmonic shaping.

What is the maximum allowable voltage on the ISENSE pin during inrush?

The absolute maximum rating for ISENSE is –0.3 V to +0.3 V. During startup, negative inrush spikes can exceed this; therefore, a 220 Ω series resistor is recommended between the sense resistor and ISENSE to limit reverse current to within safe limits and prevent latch-up or damage.
