Product details
Overview
ICE2A0565ZHKLA1 from Infineon Technologies is an off-line AC/DC current-mode PWM controller with integrated 650V CoolMOS™ power transistor, designed for flyback SMPS in low-power standby applications. It delivers 23W output at 230VAC ±15%, operates at 100kHz switching frequency, features <±5% peak current limiting tolerance, and supports auto-restart protection during overload or open-loop faults.
For engineers reviewing the ICE2A0565ZHKLA1 datasheet, ICE2A0565ZHKLA1 pinout, ICE2A0565ZHKLA1 application, or ICE2A0565ZHKLA1 equivalent, key selection criteria include integrated high-voltage MOSFET capability, precise current sensing accuracy, thermal shutdown with auto-restart behavior, and DIP-7 package creepage compliance for universal-input offline converters.
Technical Context
The ICE2A0565ZHKLA1 integrates a 650V avalanche-rugged CoolMOS™ transistor with a current-mode PWM controller featuring leading-edge blanking, propagation delay compensation, and internal 1.25V reference. Its oscillator supports fixed 100kHz operation with frequency reduction to 20–21.5kHz in standby to suppress audible noise.
Protection functions are centralized in a dedicated unit enabling auto-restart on overvoltage (no-load), overload (short-circuit), and thermal shutdown events. The Isense pin directly monitors source current of the integrated MOSFET, while SoftS controls both startup soft-start timing and auto-restart duty cycle via external capacitor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 650V - Enables direct rectified mains connection without external HV MOSFET, supporting 85–265VAC input range. |
| fSW | 100kHz - Fixed-frequency operation balances efficiency and transformer size; reduced to 20–21.5kHz in standby to avoid acoustic noise. |
| RDS(on) | 4.7Ω @ Tj = 25°C - Defines conduction loss and thermal rise; enables 23W continuous output at Ta = 75°C with 6cm² PCB copper. |
| Current Limit Tolerance | <±5% - Ensures consistent transformer and secondary diode sizing across production lots, reducing BOM cost variance. |
| Soft-Start Control | User-defined via external capacitor on SoftS pin - Prevents inrush current and stabilizes VCC ramp during startup. |
| Protection Mode | Auto-restart - Cycles on fault detection (overload, open loop, overvoltage) with controlled off-time, avoiding latch-off failure mode. |
Pinout & Package
ICE2A0565ZHKLA1 uses the PG-DIP-7-1 package - a 7-pin dual-in-line plastic package with isolated drain pins and enhanced creepage distance for reinforced insulation in universal-input offline designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | SoftS | Soft-start timing and auto-restart control node; external capacitor sets startup ramp and fault recovery period. |
| 2 | FB | Feedback input for primary-side regulation; connects to optocoupler emitter to close voltage loop without secondary-side TL431. |
| 3 | Isense | Current sense input referenced to GND; monitors voltage across source resistor to trigger cycle-by-cycle current limit. |
| 4 | N.C. | No internal connection; electrically floating; must remain unconnected per design rules. |
| 5 | Drain | High-voltage drain terminal of integrated 650V CoolMOS™; connects directly to transformer primary and bulk capacitor. |
| 7 | VCC | Controller supply input (8.5–21V); powers internal logic and gate driver; disabled above 16.5V during startup for overvoltage protection. |
| 8 | GND | Primary-side ground reference for control circuitry and Isense measurement; separate from power ground plane per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 650V CoolMOS™ | Eliminates external HV MOSFET and associated gate drive components, reducing component count and board area by ≥30% vs discrete solutions. |
| Precise peak current limit (<±5%) | Enables accurate transformer turns ratio and secondary diode rating selection, minimizing margin-driven overdesign and cost. |
| Standby frequency reduction (20–21.5kHz) | Maintains stable output regulation below 30mW no-load consumption while avoiding audible coil whine in consumer electronics. |
| Auto-restart protection suite | Provides fail-safe response to open-loop, overvoltage, and overload conditions without requiring external latching circuitry. |
| Enhanced creepage in DIP-7 | Meets IEC/EN 60950-1 reinforced insulation requirements for 230VAC systems without additional slotting or spacing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar off-line flyback controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ICE2A0565G | PG-DSO-16/12 package; same 650V/100kHz/4.7Ω specs but surface-mount; higher thermal resistance than DIP-7. | Preferred for automated SMT assembly; requires thermal pad and solder mask defined for heat dissipation. | Select when board space is constrained and reflow compatibility is required; verify RthJA meets 75°C ambient derating. |
| ICE2B0565Z | Same PG-DIP-7-1 package but 67kHz switching frequency; identical RDS(on), VDS, and protection features. | Better EMI profile at lower frequency; slightly larger magnetics needed; lower switching loss at high load. | Choose for noise-sensitive applications (audio equipment) or where transformer core loss dominates over copper loss. |
Compared with ICE2A0565G and ICE2B0565Z, ICE2A0565ZHKLA1 offers optimal balance of through-hole manufacturability, audible-noise-free standby, and compact transformer sizing-making it ideal for cost-sensitive, high-volume AC/DC adapters requiring regulatory compliance and field robustness.

FAQ
What is the maximum continuous output power of ICE2A0565ZHKLA1 at 75°C ambient?
The ICE2A0565ZHKLA1 delivers 23W continuous output power at Ta = 75°C, Tj = 125°C, with 6cm² copper area on the PCB. This rating assumes standard DIP-7 mounting and natural convection cooling-no heatsink required. Derating applies above 75°C ambient per the thermal curves in Section 4.2 of the datasheet.
How does the SoftS pin control auto-restart behavior during fault conditions?
The SoftS pin sets both startup soft-start time and auto-restart off-time using a single external capacitor. During fault detection (e.g., overload), the controller enters auto-restart mode and disables switching until the SoftS capacitor discharges below threshold; then it attempts restart. The capacitor value directly determines retry interval-typically 10–100nF for 0.5–5s cycles.
Can ICE2A0565ZHKLA1 operate without an optocoupler in primary-side regulation?
No-ICE2A0565ZHKLA1 requires optocoupler-based feedback via the FB pin for closed-loop voltage regulation. It lacks primary-side sensing circuitry (e.g., auxiliary winding sampling or ZCD detection). The FB pin interfaces directly with the optocoupler emitter to adjust duty cycle based on secondary-side error signal.
What is the purpose of the N.C. pin (Pin 4) in the PG-DIP-7-1 package?
Pin 4 is internally not connected and must remain unconnected on the PCB. It serves mechanical and creepage-enhancement purposes-increasing isolation distance between Drain (Pin 5) and Isense (Pin 3) to meet reinforced insulation requirements for 230VAC applications per IEC 60950-1.
