Product details

Overview

ICE3A0565Z from Infineon Technologies is a fully integrated off-line SMPS current-mode controller with built-in 650V depletion-mode CoolMOS™ power transistor and high-voltage startup cell, housed in PG-DIP-7-1 package. It delivers 25W continuous input power at 230VAC ±15%, operates at fixed 100kHz switching frequency, features <±5% peak current limiting tolerance, and achieves <100mW standby power via Active Burst Mode - used in compact AC/DC adapters and auxiliary power supplies.

For engineers reviewing the ICE3A0565Z datasheet, ICE3A0565Z pinout, ICE3A0565Z application, or ICE3A0565Z equivalent, key selection criteria include its integrated 650V CoolMOS™, DIP-7 isolation layout, adjustable blanking window for load-jump immunity, Auto Restart protection modes (OVP, OTP, OLP), and soft-driving gate driver for EMI reduction.

Technical Context

The ICE3A0565Z implements a current-mode PWM control architecture with internal oscillator fixed at 100kHz and precise leading-edge blanking to suppress noise during MOSFET turn-on. Its control unit integrates feedback-based Active Burst Mode activation and Auto Restart protection for overtemperature, overvoltage, overload, open-loop, and VCC undervoltage conditions.

It combines a 650V avalanche-rugged depletion CoolMOS™ transistor with an integrated startup cell that draws current directly from rectified AC line, eliminating external high-voltage resistors. The drain-connected pins (Pin 5) are internally isolated from controller ground, enabling safe high-side switching in flyback topologies without external level-shifting circuitry.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	650V - supports universal AC input (85–265VAC) without external voltage clamping
f_SW	100kHz fixed - enables compact transformer design and predictable EMI profile
R_DS(on)	4.70Ω @ 25°C - determines conduction loss and thermal derating in 25W continuous operation
I_LOAD max	25W @ 230VAC ±15% - defines maximum continuous output capability in open-frame design
Current limit tol.	<±5% - ensures consistent transformer sizing and secondary diode selection across production lots
Standby power	<100mW - meets Energy Star Level VI and EU CoC Tier 2 no-load requirements
Duty cycle max	72% - sets practical duty ratio ceiling for flyback transformer turns ratio calculation

Pinout & Package

ICE3A0565Z uses the PG-DIP-7-1 package - a 7-pin dual-inline plastic package with isolated drain pad, wide creepage distance (>5mm), and RoHS-compliant lead plating. Pin 4 is not connected; pins 5 (Drain) and 7 (VCC) are electrically isolated from GND (Pin 8) and CS (Pin 3), supporting primary-side high-voltage switching without external isolation components.

Pin/Terminal	Circuit Role	Design Meaning
1	SoftS	Soft-start timing capacitor connection - controls ramp-up of PWM duty to limit inrush current
2	FB	Optocoupler feedback input - regulates output voltage by modulating burst mode frequency and duty
3	CS	Current sense node tied to CoolMOS™ source - provides real-time primary current sensing for cycle-by-cycle limiting
4	n.c.	No internal connection - must remain unconnected on PCB to avoid parasitic coupling
5	Drain	High-voltage CoolMOS™ drain terminal - connects directly to transformer primary and rectified AC line
7	VCC	Controller supply rail - powered by internal startup cell then sustained by auxiliary winding after startup
8	GND	Controller ground reference - separate from power ground; requires low-inductance local decoupling

Key Features

Feature	Design Value
Integrated 650V CoolMOS™	Eliminates discrete HV FET and gate driver, reducing BOM count and layout area in sub-30W SMPS
Active Burst Mode	Enables immediate load-step response with <1% output ripple at light load - no blackouts during transient recovery
Adjustable blanking window	Prevents false overcurrent triggering during high di/dt events (e.g., cold start, short-circuit recovery)
Auto Restart protection	System-level fault handling for OVP, OTP, OLP, open-loop, and VCC UVLO - avoids latch-up and enables self-recovery
Internal PWM leading-edge blanking	Suppresses switching noise on CS pin without external RC filter, improving reliability in noisy environments

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
ICE3A0565J	Same specs but in PG-DIP-8 package with Pins 4 & 5 internally shorted; lacks n.c. pin	Suitable where board space permits larger DIP-8 footprint and shared drain routing is acceptable	Select ICE3A0565J only if existing layout accommodates DIP-8 pinout and creepage constraints allow shared drain pins
ICE3B0565Z	67kHz fixed switching frequency; identical R_DS(on), power rating, and package	Better suited for EMI-sensitive designs requiring lower fundamental frequency and reduced core loss at high temperature	Choose ICE3B0565Z when optimizing for thermal performance in enclosed enclosures or stricter conducted EMI limits

Compared with ICE3A0565J and ICE3B0565Z, the ICE3A0565Z offers optimal balance of size (DIP-7), EMI (100kHz), and layout flexibility (isolated drain), making it preferred for space-constrained, cost-sensitive 25W adapters requiring rapid load-step response.

FAQ

What is the maximum continuous output power achievable with ICE3A0565Z?

The ICE3A0565Z supports up to 25W continuous input power at 230VAC ±15% in open-frame design at T_a=50°C and T_j=125°C with R_thCA=2.7K/W. Real-world output power depends on transformer efficiency, cooling, and safety margins - typical 5V/3A or 12V/2A designs achieve 15–20W sustained output.

Does ICE3A0565Z require an external startup resistor?

No. ICE3A0565Z integrates a high-voltage startup cell that draws current directly from the rectified AC line through the Drain pin, eliminating the need for external high-voltage resistors and associated power loss and reliability risks.

How does the adjustable blanking window improve system reliability?

The adjustable blanking window disables current-sense detection for a user-defined duration after each PWM pulse, preventing false overcurrent trips caused by transformer leakage inductance spikes or diode reverse recovery noise - critical for stable operation during cold starts or output short-circuit recovery.

Can ICE3A0565Z be used in quasi-resonant (QR) flyback designs?

No. ICE3A0565Z operates at fixed 100kHz frequency and does not support zero-voltage switching detection or variable-frequency QR control. It is designed for continuous conduction mode (CCM) or discontinuous conduction mode (DCM) flyback topologies with constant-frequency PWM regulation.
