Product details

Overview

ICE2B0565 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 23W output power at 230VAC ±15%, operates at 67kHz switching frequency, features 4.7Ω R_DS(on), and supports low-power standby mode compliant with European Commission requirements.

For engineers reviewing the ICE2B0565 datasheet, ICE2B0565 pinout, ICE2B0565 application, or ICE2B0565 equivalent, key selection considerations include its integrated high-voltage power stage, precise ±5% peak current limiting, auto-restart protection architecture, and DIP-8 package suitability for cost-sensitive, open-frame power supplies under 30W.

Technical Context

The ICE2B0565 implements a current-mode PWM control architecture with internal leading-edge blanking, propagation delay compensation, and a dedicated protection unit that triggers auto-restart on overload, open-loop, or overvoltage faults. Its oscillator supports fixed 67kHz operation with frequency reduction to 20–21.5kHz in standby to suppress audible noise.

It integrates a 650V avalanche-rugged CoolMOS™ transistor with isolated drain in TO220 variants (not applicable to DIP-8), and uses a single external sense resistor for adjustable peak current limitation. The feedback path directly interfaces with optocoupler-based secondary-side regulation while maintaining primary-side current sensing via the Isense pin.

Key Specifications

Parameter	Value and Actual Design Meaning
Switching Frequency	67 kHz - Fixed-frequency operation optimized for EMI filtering and transformer design in sub-30W flyback topologies.
R_DS(on)	4.7 Ω @ T_j = 25°C - Enables 23W continuous output at 230VAC without heatsink in DIP-8 package.
V_DS Rating	650 V - Avalanche-rugged CoolMOS™ withstands line transients and enables universal input (85–265 VAC) operation.
Peak Current Limit Tolerance	< ±5% - Tight tolerance allows smaller transformer and secondary diode sizing, reducing BOM cost and footprint.
Standby Power Dissipation	Lowest in class for DIP-8 - Achieved via frequency reduction to 20–21.5 kHz, meeting EU CoC Tier 2 and ERP Lot 6 requirements.
Protection Features	Auto-restart on overload, open-loop, overvoltage, and thermal shutdown - Eliminates need for external latch or timer circuits.
V_CC Operating Range	8.5 V to 21 V - Supports wide-range auxiliary winding design; overvoltage disable at >16.5 V during startup prevents latch-up.

Pinout & Package

ICE2B0565 is supplied in PG-DIP-8 package (8-pin dual in-line plastic), with creepage-enhanced layout suitable for reinforced insulation in Class II applications. Pin 6 is internally unconnected (N.C.).

Pin/Terminal	Circuit Role	Design Meaning
1: SoftS	Soft-start & Auto-restart control	External capacitor sets soft-start time; also controls auto-restart interval after fault detection.
2: FB	Feedback input	Receives optocoupler signal to regulate output voltage; feeds both PWM comparator and protection unit.
3: Isense	Current sense input	Monitors voltage across external source resistor to implement cycle-by-cycle current limiting and current-mode control.
4 & 5: Drain	CoolMOS™ drain terminals	Dual-drain pins reduce PCB trace inductance and improve EMI performance in high-dI/dt switching.
6: N.C.	No connection	Internally unconnected; must remain floating - no routing or soldering required.
7: VCC	Controller supply	Accepts 8.5–21 V DC; powers internal logic and gate driver; disables output if >16.5 V during startup.
8: GND	Controller ground	Primary-side reference node for all internal circuitry; requires low-inductance connection to source return path.

Key Features

Feature	Design Value
Integrated 650V CoolMOS™	Eliminates external HV MOSFET and associated gate drive components, reducing component count by ≥4 in typical flyback designs.
Precise peak current limit (<±5%)	Enables accurate transformer turns ratio selection and consistent current limiting across temperature and production lots.
Frequency reduction in standby	Lowers switching losses and audible noise by scaling frequency to 20–21.5 kHz when load drops below ~10% of rated output.
Auto-restart protection unit	Automatically recovers from short-circuit, open-loop, or overvoltage faults without requiring manual reset or external circuitry.
Leading-edge blanking & delay compensation	Rejects switch-node noise spikes and compensates for propagation delays, ensuring stable current sensing at high duty cycles.

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
ICE2A0565	Same DIP-8 package and 650V CoolMOS™, but 100kHz switching frequency and identical R_DS(on)/power rating.	Better suited for higher-efficiency, lower-output-ripple designs where EMI filtering is prioritized over audible noise suppression.	Select ICE2A0565 when target efficiency >85% at full load and audible noise is not a constraint.
ICE2B165	Same 67kHz frequency and DIP-8 package, but lower 3.0Ω R_DS(on), enabling 31W output at 230VAC.	Supports higher-power applications such as multi-output adapters or industrial control power rails requiring >25W.	Choose ICE2B165 when system output power exceeds 23W but remains within 31W and board space is unchanged.

Compared with ICE2A0565, ICE2B0565 trades higher-frequency efficiency for lower audible noise and reduced EMI filter size; compared with ICE2B165, it offers tighter cost control and thermal margin at lower power levels without sacrificing protection robustness.

FAQ

What is the maximum continuous output power achievable with ICE2B0565 in open-frame design?

The ICE2B0565 delivers up to 23W continuous output power at 230VAC ±15% under defined thermal conditions: T_a = 75°C, T_j = 125°C, and 6 cm² copper area on PCB. This rating assumes proper layout, adequate airflow, and use of recommended snubber and transformer designs per Infineon Application Note AN2013-07.

How does the auto-restart protection behave during sustained overload?

Upon detecting overload, open-loop, or overvoltage, ICE2B0565 enters auto-restart mode: it disables switching, waits a fixed internal timeout (~1 s), then attempts soft-start recovery. If the fault persists, the cycle repeats indefinitely without latching - enabling automatic recovery once the fault condition clears.

Can ICE2B0565 operate with discontinuous conduction mode (DCM) flyback topologies?

Yes - ICE2B0565 supports both continuous and discontinuous conduction mode flyback operation. Its current-mode control architecture and leading-edge blanking ensure stable regulation across DCM transitions, especially critical in low-load and light-load conditions common in standby power applications.

Is external current-sense resistor required, and what tolerance is recommended?

An external current-sense resistor is mandatory on the CoolMOS™ source path to generate the Isense voltage. A 1% metal-film resistor is recommended to maintain the overall peak current limit accuracy within the specified <±5% tolerance, as resistor drift and PCB trace resistance directly impact current threshold precision.
