Product details
Overview
ICE2A180Z from Infineon Technologies is an off-line AC/DC current-mode PWM controller with integrated 800V CoolMOS™ power transistor in PG-DIP-7-1 package, delivering 29W at 230VAC ±15% and 17W at 85–265VAC with 100kHz switching frequency, RDS(on) = 3.0Ω, and precise ±5% peak current limiting - used in low-power standby SMPS for consumer adapters and auxiliary supplies.
For engineers reviewing the ICE2A180Z datasheet, ICE2A180Z pinout, ICE2A180Z application, or ICE2A180Z equivalent, key selection considerations include its 800V drain rating, auto-restart protection architecture, adjustable current limit via external resistor, and DIP-7 footprint compatibility with board-level creepage requirements.
Technical Context
The ICE2A180Z integrates a 800V avalanche-rugged CoolMOS™ transistor and current-mode PWM controller in a single PG-DIP-7-1 package, eliminating external high-voltage MOSFET and gate driver. Its control loop uses feedback voltage (FB) to regulate duty cycle while Isense monitors source current for cycle-by-cycle overcurrent protection.
It implements frequency reduction in standby mode (down to 20–21.5kHz) to meet EU energy efficiency requirements, and features thermal shutdown with auto-restart, leading-edge blanking, and user-defined soft-start via external capacitor on SoftS pin - all without requiring a heatsink in DIP-7 configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 800V - Enables direct rectified mains operation up to 380V DC without external HV MOSFET. |
| fSW | 100kHz - Fixed switching frequency enabling predictable EMI filter design and transformer sizing. |
| RDS(on) | 3.0Ω @ Tj = 25°C - Determines conduction loss and thermal rise in primary-side power stage. |
| Peak Current Limit Tolerance | < ±5% - Enables accurate transformer and output diode derating for cost-optimized system design. |
| Standby Power Dissipation | Lowest in class for DIP-7 - Meets < 30mW no-load requirement per EU CoC v5 Tier 2 without auxiliary winding. |
| Protection Modes | Auto-restart on overload, open-loop, overvoltage, and thermal shutdown - eliminates latch-off failure modes in unattended systems. |
| Soft-Start Control | User-defined via external capacitor on SoftS pin - prevents inrush current stress on input bulk capacitor and transformer. |
Pinout & Package
ICE2A180Z is housed in a PG-DIP-7-1 (7-pin dual in-line plastic) package with creepage-enhanced layout and isolated drain terminals. Pin 1 is SoftS, Pin 2 is FB, Pin 3 is Isense, Pin 4 is N.C., Pin 5 is Drain (800V), Pin 7 is VCC, and Pin 8 is GND - note Pin 6 is omitted (7-pin variant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SoftS) | Soft-start timing & auto-restart control | External capacitor sets startup ramp time; also triggers restart delay after fault detection. |
| 2 (FB) | Primary-side regulation feedback input | Connects to optocoupler emitter to close voltage loop; internal comparator compares to 2.5V reference. |
| 3 (Isense) | Current sense input (CoolMOS™ source node) | Senses voltage across external shunt resistor to enable cycle-by-cycle peak current limiting. |
| 4 (N.C.) | No connection | Internally unconnected; must remain floating or grounded per layout guidelines to avoid noise coupling. |
| 5 (Drain) | High-voltage drain of integrated CoolMOS™ | Directly connects to rectified AC input (up to 800V); requires ≥4mm creepage clearance on PCB. |
| 7 (VCC) | Controller supply rail | Powered by auxiliary winding; operates 8.5–21V; disables driver above 16.5V during startup for OVP. |
| 8 (GND) | Primary-side ground reference | Common return for controller logic, Isense, FB, and SoftS; must be separated from power ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 800V CoolMOS™ | Eliminates discrete HV MOSFET and driver, reducing BOM count and layout complexity in flyback converters. |
| Precision ±5% current limiting | Enables smaller transformer core and lower-cost secondary diode without compromising short-circuit robustness. |
| Frequency reduction in standby | Lowers switching losses to achieve <30mW no-load power, meeting EU CoC v5 Tier 2 and Energy Star 3.0. |
| Auto-restart protection suite | Recovers autonomously from overload, open-loop, overvoltage, and thermal faults - improves field reliability. |
| Adjustable soft-start | External capacitor on SoftS pin controls ramp rate, preventing transformer saturation and input capacitor stress. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar off-line SMPS controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ICE2A165 | 650V drain rating, same DIP-8 package but higher RDS(on) (3.0Ω vs. ICE2A180Z's 3.0Ω at 800V), lower max power (18W vs. 17W at universal input) | Requires input derating above 265VAC; unsuitable for 277VAC or surge-prone mains environments | Select ICE2A165 only when input is strictly limited to ≤265VAC and cost is prioritized over surge margin. |
| ICE2A280Z | Same 800V rating and DIP-7-1 package, but lower RDS(on) (0.8Ω), higher power capability (31W at 230VAC) | Delivers higher continuous output with same footprint; requires larger heatsinking only above 25W load | Choose ICE2A280Z when scaling output power beyond 17W while retaining layout compatibility and protection features. |
Compared with ICE2A165, ICE2A180Z provides essential 800V surge tolerance for global mains compliance; compared with ICE2A280Z, it offers optimal cost-performance balance for sub-20W applications where lower conduction loss is unnecessary.

FAQ
What is the maximum continuous output power achievable with ICE2A180Z in a standard DIP-7 open-frame design?
The ICE2A180Z delivers 17W continuous output power at 85–265VAC input with Ta = 75°C, Tj = 125°C, and 6 cm² copper area on PCB. This rating assumes proper thermal layout, adequate creepage, and use of recommended snubber and feedback components per Infineon Application Note AN2013-09.
Does ICE2A180Z require an external startup resistor, and what is the VCC operating range?
Yes - ICE2A180Z requires an external high-voltage startup resistor (typically 1–2 MΩ) from rectified mains to VCC until the auxiliary winding takes over. The VCC supply operates from 8.5V to 21V, with internal overvoltage protection disabling the driver above 16.5V during startup.
How is the peak current limit adjusted, and what is its accuracy across temperature?
Peak current limit is set by an external sense resistor between Isense and GND; threshold is internally fixed at 0.52V. Total tolerance is <±5% over -25°C to +125°C, including propagation delay compensation and leading-edge blanking, as verified in Table 12 of the V2.10a datasheet.
Can ICE2A180Z be used in non-isolated buck-derived topologies like buck-PFC or flyback with primary-side regulation?
No - ICE2A180Z is designed exclusively for isolated flyback topologies with optocoupler-based feedback. Its FB pin interface, protection architecture, and current-sense path assume transformer isolation; it lacks the control logic or pinout required for primary-side regulation or buck-derived PFC stages.
