Product details
Overview
ICE1PCS01GFUMA1 from Infineon Technologies is an 8-pin Continuous Conduction Mode (CCM) Power Factor Correction (PFC) controller IC for boost-topology AC-DC front-ends, supporting universal input (85–265 VAC), programmable switching frequency (50–250 kHz), average current control, and Class D IEC 61000-3-2 compliance in lighting ballasts and industrial SMPS.
For engineers reviewing the ICE1PCS01GFUMA1 datasheet, ICE1PCS01GFUMA1 pinout, ICE1PCS01GFUMA1 application, or ICE1PCS01GFUMA1 equivalent, key selection criteria include its external voltage/current loop compensation flexibility, 95% max duty cycle at 125 kHz, trimmed 5 V ±2% internal reference, brown-out protection, and gate drive capability of 1.5 A source/sink with 11.5 V clamp.
Technical Context
The ICE1PCS01GFUMA1 implements a cascaded dual-loop control architecture: an inner average current loop (using ISENSE and ICOMP) shapes sinusoidal input current, while the outer voltage loop (via VSENSE and VCOMP) regulates output bus voltage. It operates exclusively in CCM under normal load, transitioning to DCM only at light loads - maintaining harmonic distortion within IEC 61000-3-2 Class D limits.
Its soft-start function sources a constant 10.8 µA into the VCOMP network, linearly ramping gate drive amplitude to limit inrush stress on the boost diode. Protection logic integrates brown-out detection (VCC < 10.2 V), peak current limiting (via ISENSE), open-loop detection (VSENSE < 0.8 V), and output under-voltage (OUV) monitoring - all with dedicated comparator thresholds and deglitched fault latching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Topology Support | Boost converter only; requires external MOSFET and diode - no integrated power switch. |
| Input Voltage Range | 85–265 VAC universal line; enables single-design global deployment without hardware change. |
| Switching Frequency | 50–250 kHz via resistor on FREQ pin; allows EMI tuning and magnetics optimization. |
| Max Duty Cycle | 95% typical at 125 kHz; supports high step-up ratios in wide-input PFC stages. |
| Voltage Reference | 5.0 V ±2% trimmed internal reference at VSENSE; ensures precise OUV, OVP, and regulation accuracy. |
| Gate Drive Strength | 1.5 A source/sink with 11.5 V clamp; directly drives medium-power MOSFETs without buffer stage. |
| Protection Features | Brown-out (VCC UVLO: 10.2 V off / 11.2 V on), OUV, OVP, peak current limit, open-loop detect, soft over-current. |
Pinout & Package
ICE1PCS01GFUMA1 is housed in PG-DSO-8 (SOIC-8) package, surface-mount, RoHS-compliant, with standard 1.27 mm pitch and exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Signal Ground Reference | Common return for all analog and digital circuitry; must be low-impedance connection to system ground plane. |
| 2 ICOMP | Current Loop Compensation Node | Connects external RC network to stabilize inner current loop; integrates OTA2 output for average current regulation. |
| 3 ISENSE | Primary Current Sense Input | Accepts voltage drop across external shunt resistor (R1); feeds both average current control and cycle-by-cycle peak limiting. |
| 4 FREQ | Frequency Programming Input | Resistor-to-ground sets oscillator frequency; 50–250 kHz range enables EMI spread-spectrum design. |
| 5 VCOMP | Voltage Loop Compensation & Soft-Start Node | Hosts external compensation network; 10.8 µA soft-start current ramps VCOMP linearly to limit inrush. |
| 6 VSENSE | Output Bus Voltage Feedback Input | Monitors scaled VOUT via resistive divider; 5 V reference enables accurate regulation and OUV/OVP thresholds. |
| 7 VCC | IC Power Supply Input | Requires external auxiliary supply (10–21 V); UVLO activates at 10.2 V (off) / 11.2 V (on). |
| 8 GATE | High-Current Gate Driver Output | Drives external MOSFET gate directly; 1.5 A sink/source with 11.5 V clamp prevents gate overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| Average Current Control Architecture | Enables near-unity PF (>0.99) across full load and line range without complex digital computation. |
| External Dual-Loop Compensation | Independent ICOMP and VCOMP pins allow full customization of current/voltage loop bandwidth and phase margin. |
| Programmable Switching Frequency | Resistor-set 50–250 kHz operation permits trade-off between efficiency, size, and EMI compliance. |
| Dedicated Brown-Out Protection | Monitors VCC to disable gate drive before input rectifier collapse - prevents uncontrolled boost operation. |
| Nonlinear Gain Block | Compensates for line-voltage-dependent duty cycle variation, ensuring consistent current shaping at low/high line. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CCM PFC controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ICE2PCS01G | Successor with improved startup current (100 µA vs. 200 µA), lower VCC UVLO hysteresis (0.5 V vs. 1.0 V), and integrated soft-start timer. | Preferred for new designs targeting higher light-load efficiency and tighter brown-out hysteresis control. | Select ICE2PCS01G if upgrading for reduced standby power and enhanced transient immunity; not pin-compatible due to revised VCOMP behavior. |
| UCC28070 | Two-phase interleaved CCM controller with internal PWM modulator; requires no external oscillator; supports 30–300 kHz. | Suitable for >600 W systems where interleaving reduces input/output ripple and EMI. | Choose UCC28070 only when doubling power capacity or requiring interleaved topology; adds complexity in layout and component count. |
Compared with ICE2PCS01G, ICE1PCS01GFUMA1 offers proven field reliability and simpler compensation but lacks adaptive light-load modes; versus UCC28070, it provides lower BOM cost and smaller footprint for single-phase ≤300 W designs, though without phase interleaving benefits.

FAQ
What is the minimum recommended series resistor for the ISENSE pin?
A 220 Ω resistor is recommended between the external sense resistor and ISENSE pin to limit inrush current during startup, preventing damage from voltage spikes exceeding absolute maximum ratings. This value is specified in the datasheet's Pin Functionality section and validated across 85–265 VAC input transients.
Does ICE1PCS01GFUMA1 support Discontinuous Conduction Mode (DCM)?
No - ICE1PCS01GFUMA1 is designed exclusively for Continuous Conduction Mode (CCM) operation. Under very light loads, the system may naturally enter DCM due to inductor current decay, but the IC does not regulate or optimize for DCM; performance guarantees apply only in CCM per datasheet test conditions.
Can VCOMP be used for external synchronization?
No - VCOMP is strictly an internal voltage loop compensation node and soft-start integrator; it is not designed for synchronization. The IC lacks a SYNC pin or external clock input. Frequency is set solely via the FREQ pin resistor, and no master-slave or external clocking capability is supported.
Is the GATE output compatible with 12 V logic-level MOSFETs?
Yes - the GATE pin delivers 1.5 A peak source/sink current with a clamped output voltage of 11.5 V (typical), making it fully compatible with standard 12 V gate-rated MOSFETs. No level-shifting or external gate driver is required for devices with VGS(th) ≤ 4 V and Qg ≤ 40 nC.
