Product details
Overview
ICE3B2065HKLA1 from Infineon Technologies is a 650V off-line SMPS current-mode controller IC with integrated depletion-mode CoolMOS™ and startup cell, housed in PG-DIP-8 package. It delivers 57W input power at 230VAC ±15%, operates at fixed 67kHz switching frequency, features ±5% peak current limiting tolerance, and enables <100mW standby power via Active Burst Mode - used in AC/DC adapters and open-frame power supplies.
For engineers reviewing the ICE3B2065HKLA1 datasheet, ICE3B2065HKLA1 pinout, ICE3B2065HKLA1 application, or ICE3B2065HKLA1 equivalent, key selection considerations include its integrated 650V CoolMOS™, Auto Restart protection modes (overtemperature, overvoltage, open-loop), adjustable blanking window for load-jump immunity, and DIP-8 isolation-compliant layout for Class II designs.
Technical Context
The ICE3B2065HKLA1 implements a current-mode PWM control architecture with internal oscillator set to 67kHz, precise leading-edge blanking, and propagation delay compensation for stable peak-current sensing. Its integrated CoolMOS™ drain-source path supports direct high-voltage startup without external resistor networks.
Control logic includes dedicated SoftS pin for user-defined soft-start timing, FB pin for optocoupler-based voltage regulation, and CS pin that serves dual role as current sense input and CoolMOS™ source terminal - enabling single-point ground reference and simplified transformer design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switching Frequency | Fixed 67 kHz - ensures EMI compliance in standard conducted noise bands and simplifies filter design. |
| Max Input Power (230VAC) | 57 W - defines maximum continuous output capability in open-frame design at Ta=75°C, Tj=125°C. |
| RDS(on) | 0.92 Ω @ 25°C - determines conduction loss and thermal rise in primary-side MOSFET section. |
| Peak Current Limit Tolerance | ±5% - enables accurate transformer sizing and consistent overload protection across temperature. |
| Standby Power | <100 mW - achieved via Active Burst Mode, meeting Energy Star Level VI and EU CoC Tier 2 requirements. |
| Protection Modes | Auto Restart for overtemperature, VCC overvoltage, open-loop, overload, and VCC undervoltage - eliminates latch-off failure mode and improves field reliability. |
| Startup Cell | Integrated 650V depletion CoolMOS™ startup cell - removes need for high-voltage startup resistor, reducing BOM count and leakage paths. |
Pinout & Package
Package: PG-DIP-8 (8-pin plastic dual in-line package with internal drain short between pins 4 and 5; creepage distance optimized for reinforced insulation per IEC 60950-1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | SoftS | Soft-start timing capacitor connection - controls ramp-up of PWM duty cycle to limit inrush current. |
| 2 | FB | Optocoupler feedback input - regulates output voltage by modulating duty cycle based on secondary-side error signal. |
| 3 | CS | Current sense / CoolMOS™ source - provides primary-side current feedback and establishes source reference for integrated MOSFET. |
| 4 & 5 | Drain | High-side 650V CoolMOS™ drain terminals - internally shorted; connects directly to bulk capacitor and transformer primary. |
| 6 | n.c. | No connect - unused pin; must remain unconnected per datasheet layout guidance. |
| 7 | VCC | Controller supply rail - powers internal logic and gate driver; requires local 10–22 µF low-ESR capacitor. |
| 8 | GND | Controller ground reference - separate from power ground; critical for noise immunity in current-sense path. |
Key Features
| Feature | Design Value |
|---|---|
| Active Burst Mode | Enables immediate load-step response with <1% output ripple at no-load - avoids blackouts during light-to-heavy load transitions. |
| Adjustable Blanking Window | Configurable via external RC on SoftS pin - prevents false triggering of current-limit protection during transient load surges. |
| Integrated Startup Cell | 650V depletion CoolMOS™ eliminates external HV startup resistor - reduces component count and improves startup efficiency. |
| Precise Peak Current Limit | ±5% tolerance over temperature - allows smaller transformer core size and lower-cost secondary rectifier selection. |
| Isolation-Compliant Layout | DIP-8 package with >8 mm creepage between drain and control pins - supports Class II (double-insulated) AC/DC designs without extra spacing. |

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 |
|---|---|---|---|
| ICE3B2065I | PG-TO220-6-46 package with isolated drain tab; RDS(on) = 3.00 Ω; higher power rating (102 W @ 230VAC). | Requires heatsink mounting and PCB cutout; suited for enclosed, thermally constrained systems. | Select when >57 W output or mandatory metal-tab thermal coupling is required. |
| ICE3B1565 | DIP-8 package; same 67 kHz frequency but RDS(on) = 1.70 Ω; max input power = 42 W @ 230VAC. | Limited to lower-power adapters (<42 W); lower conduction loss but reduced overload margin. | Select for cost-sensitive, sub-42 W designs where thermal headroom is sufficient. |
Compared with ICE3B2065I and ICE3B1565, the ICE3B2065HKLA1 uniquely balances 57 W capability, DIP-8 isolation compliance, and <100 mW standby - making it optimal for Class II, open-frame, mid-power AC/DC converters where board space and safety spacing are prioritized over maximum wattage.

FAQ
What is the purpose of the n.c. pin (Pin 6) in the PG-DIP-8 package?
Pin 6 is explicitly designated as "Not Connected" in the official Infineon datasheet and must remain unconnected on the PCB. It serves no electrical function and is not internally bonded; routing traces or placing components on this pin violates layout guidelines and may compromise creepage/clearance compliance.
Can ICE3B2065HKLA1 operate without an external soft-start capacitor?
No - the SoftS pin (Pin 1) requires an external capacitor (typically 10–100 nF) to set soft-start duration. Omitting it causes uncontrolled duty-cycle ramp-up, risking transformer saturation and MOSFET overcurrent during power-on, as confirmed in Section 3.6.2 of the datasheet.
How does the integrated startup cell eliminate the need for an external HV resistor?
The internal depletion-mode CoolMOS™ acts as a self-biasing high-voltage current source: it conducts during initial bulk capacitor charging, delivering ~1 mA to VCC until the auxiliary winding takes over. This replaces the typical 1–2 MΩ, 1 W startup resistor, reducing heat generation and improving startup efficiency above 100 VAC.
What is the minimum recommended VCC bypass capacitance?
A minimum of 10 µF low-ESR aluminum or tantalum capacitor is required across VCC and GND (Pin 7–8), as specified in Section 4.3.2 of the datasheet. Lower values risk VCC droop during peak gate drive, causing intermittent shutdown or erratic burst-mode behavior under dynamic load conditions.
