ICE2PCS02GXUMA1 Обзор
A PFC (Power Factor Correction) controller is a critical analog IC used in AC-DC power supplies to shape the input current waveform so it tracks the AC line voltage. By switching a boost converter at high frequency and modulating the duty cycle to follow the rectified mains, the controller forces the input current to look sinusoidal and in phase with the voltage. This reduces harmonic distortion (THD), helps the end product meet regulatory standards such as IEC 61000-3-2, and improves the real power drawn from the AC mains. PFC sits in the power management IC hierarchy under AC-DC controllers, alongside flyback controllers and LLC resonant controllers.
Key features of the ICE2PCS02GXUMA1 include a wide supply range for VCC, internal soft-start, undervoltage lockout (UVLO), over-voltage protection on the feedback pin, and open-loop detection. Its average current control architecture rejects line-frequency disturbances, providing stable operation in CCM under heavy loads. Compared to the earlier ICE1PCS01/02 generation, the trimmed 3V reference tightens output regulation accuracy, and the BiCMOS design reduces quiescent current draw.
Typical applications include 80 PLUS-compliant PC silver/gold ATX power supplies, server SMPS modules, industrial SMPS with universal mains input (90-264 VAC), flat-panel TV power boards, and LED driver front-end stages requiring low THD. The 8-pin PG-DSO package with exposed pad offers excellent thermal dissipation in a small PCB area, and the wide frequency range enables optimization between magnetic size and switching loss.

Типичное применение
ICE2PCS02GXUMA1 подходит для 6 применениеs: ATX PC Power Supply PFC Stage, Industrial SMPS Universal Mains Input, Server and Datacenter SMPS, Flat-Panel TV and Display Power Board, LED Driver Front-End Stage, Universal Laptop and Game Console Charger.
ATX PC Power Supply PFC Stage
The ICE2PCS02GXUMA1 is a natural fit for the PFC front-end of 80 PLUS-compliant ATX power supplies from 300 W to 1 kW. Its CCM average-current-mode control delivers PF > 0.95 and input current THD well below the IEC 61000-3-2 class-D limits across 90-264 VAC universal mains. At a 65 kHz typical switching frequency (programmable to 250 kHz via the RT pin resistor), the boost inductor and EMI filter can be sized for compact ATX enclosures. The 95% maximum duty cycle ensures the 400 VDC bulk rail stays regulated even at low-line brownout. Pair with an Infineon ICE2HS01G half-bridge controller for the downstream LLC stage to build a complete 80 PLUS Gold platform.

Industrial SMPS Universal Mains Input
In industrial SMPS modules operating from 90-264 VAC universal mains, the ICE2PCS02GXUMA1 provides robust PFC performance with its -40 C to +125 C operating range and BiCMOS process tolerance to electrical noise. The average-current-mode control rejects line-frequency disturbances that would otherwise disturb a peak-current-mode loop, giving stable 400 VDC output even with heavily distorted industrial mains. Built-in open-loop detection and output over-voltage protection prevent catastrophic failure if the feedback path is broken during maintenance. The PG-DSO-8 exposed pad enables direct PCB heatsinking without an external heatsink.

Server and Datacenter SMPS
For 1U/2U server and hyperconverged infrastructure power supplies, the ICE2PCS02GXUMA1 supports the high-efficiency PFC front-end required for 80 PLUS Titanium and 80 PLUS Platinum ratings. Its CCM topology delivers lower peak currents and better thermal distribution than CRM (critical conduction mode) alternatives, which matters in densely packed 1U chassis with restricted airflow. The programmable switching frequency up to 250 kHz allows the boost inductor to shrink to fit tight server form factors, while the high 95% max duty cycle keeps bulk-cap ripple manageable at 240 VAC / full load.
Рекомендуется
Flat-Panel TV and Display Power Board
The ICE2PCS02GXUMA1 is well suited to flat-panel TV and large-display monitor power boards that must meet ENERGY STAR standby and IEC 61000-3-2 harmonic limits. Its 8-pin PG-DSO package fits the slim TV chassis profile, and the trimmed 3V reference delivers tight bulk-rail regulation under varying LED-backlight loads. The internal soft-start limits inrush current at TV power-on, preventing nuisance tripping of household breakers. Combined with a downstream QR or flyback controller, the ICE2PCS02GXUMA1 enables a low-BOM PFC stage that does not require auxiliary windings on the boost inductor for sensing.
Рекомендуется
LED Driver Front-End Stage
High-bay and street-lighting LED drivers benefit from the ICE2PCS02GXUMA1's CCM PFC front-end to comply with harmonic current limits and improve driver efficiency. The average-current-mode control maintains near-unity PF regardless of LED string voltage variations, while the programmable switching frequency up to 250 kHz enables small magnetics for slim outdoor luminaire housings. The -40 C to +125 C operating range covers harsh outdoor lighting environments including cold-start at -30 C. The exposed thermal pad on PG-DSO-8 simplifies PCB layout in IP67 sealed luminaires.

Universal Laptop and Game Console Charger
For 90 W to 150 W universal-input laptop chargers and game console power bricks, the ICE2PCS02GXUMA1 provides a compact CCM PFC stage that pairs naturally with an Infineon CoolSET flyback. The 65 kHz typical / 250 kHz maximum switching range lets designers shrink the boost inductor to fit thin charger housings, and the integrated protection features (UVLO, open-loop detection, output OVP) reduce external component count. Compared to CRM PFC controllers, the ICE2PCS02GXUMA1 keeps EMI filter size smaller at higher power levels, which is critical for chargers that must pass EN 55022 Class B conducted emissions.

Заметки по проектированию
The ICE2PCS02GXUMA1 VCC rail must be sourced from an auxiliary winding on the boost inductor or from an external startup regulator. Bootstrap the VCC with at least 10 uF of bulk capacitance plus 100 nF of high-frequency decoupling placed within 5 mm of the VCC pin. The internal UVLO releases operation at ~12 V and re-locks below ~10 V, so the auxiliary winding must regulate above 12 V under all line/load conditions. Below this, the IC may oscillate in start-up, causing audible buzz and risking the boost MOSFET.
Although the ICE2PCS02GXUMA1 dissipates only ~250 mW under normal operation, the PG-DSO-8 exposed pad must be soldered to a ground copper pour of at least 50 mm^2 to keep junction temperature below 110 C at 85 C ambient. Estimated: at 250 mW dissipation and JEDEC EIA/JESD51 4-layer board, theta_JA is ~80 C/W giving 20 C rise - well within budget. Avoid placing heat-generating components (boost diode, MOSFET) directly above the controller's exposed pad, or the pad will conduct heat from both directions and the controller may enter thermal shutdown at high ambient.
Keep the ISENSE current-sense loop area minimal: route the sense resistor ground return directly back to the controller GND pin rather than sharing the power ground path. The current-sense resistor should be a low-inductance SMD type (e.g., 2512 size, 1% tolerance) placed within 10 mm of the ISENSE pin. Place the RT frequency-setting resistor close to the RT pin with its ground return directly to pin 2 GND. Estimated noise pickup above 50 MHz on ISENSE can cause duty cycle jitter; add 100 pF of ceramic filter capacitance if observed.
Do NOT tie VFB directly to the bulk rail: the voltage divider impedance must be in the 1-5 Mohm range to keep the controller's quiescent draw from loading the feedback network. A common mistake is using a 100 kohm divider, which biases the controller's internal current source and shifts the regulation point. Also, the COMP pin compensation network (typically type-II: 100 nF in series with 10 kohm in parallel with 4.7 nF) must match the boost converter's right-half-plane zero - use the Infineon design tool spreadsheet to compute component values for your specific L and C values.
