Product details
Overview
ICE1PCS01G from Infineon Technologies is an 8-pin standalone CCM Power Factor Correction (PFC) controller for boost-topology AC-DC front-ends, operating across 85–265 VAC input, supporting programmable switching frequency (50–250 kHz), average current control, and delivering up to 300 W with Class D IEC 61000-3-2 compliance in industrial and consumer power supplies.
For engineers reviewing the ICE1PCS01G datasheet, ICE1PCS01G pinout, ICE1PCS01G application, or ICE1PCS01G equivalent, this page delivers verified functional identity, validated pin roles, confirmed protection features (BOP, OVP, OUV, PCL), and real-world design context for PFC stage implementation in universal-input SMPS.
Technical Context
The ICE1PCS01G implements a dual-loop control architecture: an inner average current loop (using ISENSE and ICOMP) shapes sinusoidal input current in CCM, while the outer voltage loop (VSENSE/VCOMP) regulates 380–400 V DC bus. It operates exclusively in CCM under normal load, transitioning only to DCM at light loads - preserving harmonic performance per IEC 61000-3-2 Class D.
Its oscillator is resistor-programmable (pin 4/FREQ), enabling precise frequency tuning between 50 kHz and 250 kHz. The gate driver delivers 1.5 A sink/source with 11.5 V clamp, and internal UVLO activates at 11.2 V turn-on and 10.2 V shutdown, ensuring robust startup and brown-out recovery.
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 (resistor-programmed via FREQ pin); balances EMI, efficiency, and magnetics size. |
| Max Duty Cycle | 95% typical at 125 kHz; supports high step-up ratios needed for 265 VAC → 400 V DC conversion. |
| Reference Voltage | 5.0 V ±2% trimmed internal reference; ensures accurate OUV, BOP, and VSENSE threshold stability. |
| Protection Features | Brown-out (BOP), over-voltage (OVP), output under-voltage (OUV), peak current limiting (PCL), open-loop detection - all hardware-based, cycle-by-cycle or latch-off. |
| Gate Drive Capability | 1.5 A source/sink, 11.5 V clamped; directly drives medium-power MOSFETs (e.g., 600 V CoolMOS™) without buffer stage. |
Pinout & Package
ICE1PCS01G is housed in PG-DSO-8 (SOIC-8) package, RoHS-compliant, with 1.27 mm pitch and exposed pad not connected internally.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | IC Ground Reference | Primary return path for all analog and power circuits; must connect to low-impedance PCB 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 | Current Sense Input | Samples voltage drop across external shunt resistor (R1); feeds both average regulation and cycle-by-cycle peak current limit. |
| 4 FREQ | Frequency Programming Input | Resistor-to-ground sets oscillator frequency; 50–250 kHz range enables EMI optimization and thermal trade-off tuning. |
| 5 VCOMP | Voltage Loop Compensation & Soft-Start Control | Holds compensation network for outer voltage loop; linear ramp during soft-start limits inrush stress on boost diode. |
| 6 VSENSE | Output Bus Voltage Feedback | Resistive divider input referenced to 5 V; triggers OUV if <4.75 V and OVP if >5.25 V - direct hardware protection. |
| 7 VCC | IC Supply Input | 10–21 V auxiliary supply; UVLO engages at 11.2 V (turn-on) and 10.2 V (shutdown); no internal clamp - external Zener required. |
| 8 GATE | MOSFET Gate Driver Output | 1.5 A push-pull driver with 11.5 V clamp; drives gate capacitance directly - eliminates need for discrete driver stage. |
Key Features
| Feature | Design Value |
|---|---|
| Average Current Control Architecture | Enables near-unity PF (>0.99) and low THD (<5%) in CCM across full load range - meets Class D without digital assist. |
| External Dual-Loop Compensation | Independent ICOMP and VCOMP pins allow full customization of current/voltage loop dynamics - critical for transient response tuning. |
| Hardware-Based Protection Suite | Five independent, analog protection blocks (BOP, OVP, OUV, PCL, OLP) operate without firmware - ensures fail-safe operation under fault. |
| Unique Soft-Start with Controlled Ramp | 10.8 µA constant current into VCOMP generates linear bus voltage rise - prevents diode overstress and audible noise during startup. |
| Wide Operating Input Range | Validated for 85–265 VAC line; eliminates need for separate 115/230 V hardware variants in global power supply designs. |
Applications
| Industrial AC-DC Power Supplies | Consumer LED Driver Front-Ends |

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 |
|---|---|---|---|
| STMicroelectronics L6562A | Fixed 67 kHz frequency; no FREQ pin; lower gate drive (0.8 A); lacks OUV and soft-start ramp control. | Requires external OUV circuitry; less suitable for fast-transient LED drivers or wide-line-range systems needing frequency tuning. | Select when cost sensitivity outweighs frequency flexibility and advanced protection - ideal for fixed-line, low-BOM designs. |
| ON Semiconductor NCP1653 | Programmable frequency (50–250 kHz) but uses different compensation topology; 1.2 A gate drive; no open-loop detection. | Lacks OLP and has slower OUV response; requires additional components for full fault coverage in safety-critical appliances. | Prefer for legacy designs already using NCP1653 footprint; avoid where open-loop or fast OUV response is mandatory. |
Compared with L6562A and NCP1653, ICE1PCS01G uniquely combines programmable frequency, 1.5 A gate drive, hardware OUV/OLP, and linear soft-start - making it optimal for high-reliability, globally deployed PFC stages demanding minimal external components and maximum fault resilience.

FAQ
What is the minimum external auxiliary supply voltage required to start ICE1PCS01G?
The ICE1PCS01G requires a minimum VCC of 11.2 V to initiate operation, with UVLO releasing at that threshold. Below 10.2 V, the IC shuts down completely and draws only ~200 µA. An external auxiliary supply - typically derived from a winding on the main boost inductor or a dedicated flyback - must be designed to reach 11.2 V before gate drive activation.
Can ICE1PCS01G operate in discontinuous conduction mode (DCM)?
ICE1PCS01G is explicitly designed for continuous conduction mode (CCM) operation and maintains average current control in CCM across full load. Under very light loads, the system may naturally transition to DCM due to inductor current decay, but the IC does not actively control or optimize for DCM - harmonic performance remains compliant with IEC 61000-3-2 Class D even in that region.
How is output over-voltage protection (OVP) implemented on ICE1PCS01G?
OVP is implemented as a hardware comparator monitoring VSENSE against a 5.25 V threshold (5 V +5%). When exceeded, the IC immediately disables GATE output and enters latch-off state - no software or external circuitry required. Recovery requires cycling VCC or pulling VSENSE below 0.8 V to reset the protection logic.
Is a series resistor required on the ISENSE pin, and why?
Yes - a ~220 Ω series resistor is recommended between the sense resistor (R1) and ISENSE pin. During startup or overload, high inrush currents cause large voltage spikes across R1; without current limiting, these can exceed the absolute maximum rating of ±10 mA at ISENSE. The resistor protects the internal OTA2 input stage from damage while preserving signal integrity for regulation.
