Product details
Overview
ICE2B365FKLA1 from Infineon Technologies is an off-line SMPS current-mode controller with integrated 650V CoolMOS™, designed for primary-side regulation in AC/DC flyback converters. It delivers 67W continuous output power at 230VAC ±15%, operates at 67kHz switching frequency, features adjustable peak current limiting (<±5% tolerance), and supports low-power standby mode compliant with European Commission requirements.
For engineers reviewing the ICE2B365FKLA1 datasheet, ICE2B365FKLA1 pinout, ICE2B365FKLA1 application, or ICE2B365FKLA1 equivalent, this device is selected for cost-sensitive, high-efficiency offline power supplies requiring precise current sensing, auto-restart protection, and minimal external components in DIP-8 packaging.
Technical Context
The ICE2B365FKLA1 integrates a 650V avalanche-rugged CoolMOS™ transistor and a current-mode PWM controller in a single PG-DIP-8 package. Its control architecture includes internal leading-edge blanking, propagation delay compensation, and a dedicated protection unit that triggers auto-restart on overload, open-loop, or overvoltage faults.
It implements frequency reduction in standby mode (down to 20–21.5kHz) to suppress audible noise while maintaining stable output regulation. The soft-start function is user-defined via external capacitor on SoftS pin, and peak current limit is set by an external resistor connected to Isense, enabling transformer and secondary diode optimization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 650V - Enables direct rectified mains connection without external HV MOSFET; supports universal 85–265VAC input. |
| Switching Frequency | 67kHz - Fixed frequency operation balances EMI performance and transformer size for compact 67W designs. |
| RDS(on) | 0.45Ω @ Tj = 25°C - Low conduction loss enables high efficiency and eliminates heatsink requirement in DIP-8 package. |
| Max Duty Cycle | 72% - Supports wide input voltage range and high step-down ratio in flyback topologies. |
| Current Limit Tolerance | <±5% - Tight accuracy allows conservative, cost-optimized selection of sense resistor and secondary rectifier. |
| Standby Power | Lowest in class for DIP-8 - Meets EU CoC Tier 2 and DoE Level VI standby requirements without auxiliary winding. |
| Protection Modes | Auto-restart on overload, open-loop, overvoltage, thermal shutdown - Ensures safe failure behavior without latching. |
Pinout & Package
ICE2B365FKLA1 uses the PG-DIP-8 package (8-pin dual in-line plastic), with creepage-enhanced layout and isolated drain pins. Pin 4 and Pin 5 are both connected to the CoolMOS™ drain terminal; Pin 6 is not connected (N.C.).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SoftS) | Soft-start & Auto-restart control | External capacitor sets startup ramp time; also controls restart interval after fault detection. |
| 2 (FB) | Feedback input | Accepts optocoupler signal to regulate output voltage; feeds both PWM comparator and protection unit. |
| 3 (Isense) | Current sense input | Monitors voltage across source resistor of integrated CoolMOS™; triggers cycle-by-cycle current limiting. |
| 4 & 5 (Drain) | CoolMOS™ drain terminals | High-voltage switch node; dual pins reduce trace inductance and improve thermal spreading in DIP-8 footprint. |
| 6 (N.C.) | No connection | Internally unconnected; must remain floating-no PCB trace or component attachment. |
| 7 (VCC) | Controller supply | 8.5–21V operating range; internal OVP disables driver above 16.5V during startup. |
| 8 (GND) | Primary-side ground reference | Return path for controller logic, sense circuitry, and gate drive; separate from power ground plane per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 650V CoolMOS™ | Eliminates external HV MOSFET and associated gate drive complexity; reduces BOM count by ≥4 components. |
| Precise peak current limiting | <±5% tolerance enables accurate transformer turns ratio design and smaller secondary diode selection. |
| Frequency reduction in standby | Reduces switching losses to <30mW no-load consumption while avoiding audible noise (≥20kHz minimum). |
| Auto-restart protection | Non-latching fault response isolates system during sustained overloads, open-loop, or overvoltage conditions. |
| Enhanced creepage distance | DIP-8 package meets reinforced insulation requirements for Class II applications up to 300V RMS working voltage. |

FAQ
What is the maximum continuous output power of ICE2B365FKLA1 at 230VAC?
The ICE2B365FKLA1 delivers up to 67W continuous output power under standard test conditions: 230VAC ±15%, Ta = 75°C, Tj = 125°C, and 6 cm² copper area on the PCB. This rating assumes DCM flyback operation with optimized transformer design and proper thermal layout per Infineon's AN2014-03.
Does ICE2B365FKLA1 require an auxiliary winding for VCC supply?
No-ICE2B365FKLA1 supports startup from bulk capacitor via high-voltage start-up current source, eliminating the need for an auxiliary winding. VCC is maintained during normal operation by energy recovered from the transformer's auxiliary winding or an external bias supply, but startup is fully self-sufficient.
How does the auto-restart protection behave during sustained overload?
Upon detecting overload, open-loop, or overvoltage, ICE2B365FKLA1 enters auto-restart mode: the controller stops switching, discharges SoftS capacitor, then attempts restart after a fixed timeout (~1.2s). This cycle repeats until fault condition clears-preventing thermal runaway without requiring external latch circuitry.
Can ICE2B365FKLA1 be used in quasi-resonant (QR) flyback topologies?
No-ICE2B365FKLA1 operates exclusively in fixed-frequency current-mode control and lacks valley-switching detection or variable-frequency QR modulation. For QR applications, Infineon recommends the ICE5QSBGx series, which integrates zero-current detection and adaptive frequency control.
