Product details

Overview

ICE5QR1070AZXKLA1 from Infineon is a quasi-resonant AC-DC power IC integrating a 700 V avalanche-rugged CoolMOS™ and controller in a single PG-DIP-7 package, delivering up to 58 W at 220 VAC ±20% with R_DS(on) = 1.15 Ω, <100 mW standby power in Active Burst Mode, and digital zero-crossing control for low EMI - used in auxiliary power supplies for LED TVs and set-top boxes.

For engineers reviewing the ICE5QR1070AZXKLA1 datasheet, ICE5QR1070AZXKLA1 pinout, ICE5QR1070AZXKLA1 application, or ICE5QR1070AZXKLA1 equivalent, key selection criteria include integrated HV MOSFET voltage rating, burst-mode standby power threshold, ZCD-based startup timing, digital frequency reduction capability, and line OVP/brownout response behavior.

Technical Context

This device implements a cascode-configured quasi-resonant flyback controller with digital zero-crossing detection (ZCD) and programmable minimum ZC count for adaptive switching frequency across input line conditions. It uses internal PWM current-mode control with cycle-by-cycle peak current limiting and built-in soft-start via capacitor charging.

The IC integrates two die - a controller and a 700 V CoolMOS™ - sharing thermal and electrical domains but operating with independent protection logic: VCC UVLO (10 V/16 V), input OVP/brownout on VIN, output OVP via ZCD, and junction temperature monitoring with auto-restart OTP.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	700 V - supports universal AC input (85–300 VAC) with margin for surge transients in offline SMPS.
R_DS(on)	1.15 Ω @ T_J = 25°C - enables 58 W output at 220 VAC with reduced conduction loss in primary-side switch.
Standby Power	<100 mW - achieved via selectable Active Burst Mode with configurable entry/exit thresholds.
VCC Operating Range	10–25.5 V - accommodates wide bias supply variation during transient load and startup conditions.
Digital Frequency Reduction	Up to 10 zero crossings - dynamically lowers switching frequency under light load to improve efficiency and reduce audible noise.
Protection Functions	Input OVP/brownout, VCC OVP/UVP, output OVP, overload/open-loop, overtemperature - all with auto-restart behavior.

Pinout & Package

ICE5QR1070AZXKLA1 is housed in PG-DIP-7 (7-pin dual in-line plastic) package with creepage/clearance optimized for reinforced insulation in AC-DC converters.

Pin/Terminal	Circuit Role	Design Meaning
1 FB	Feedback & Burst Control	Combines optocoupler feedback signal reception, burst mode entry/exit threshold setting, and overload detection.
2 VIN	Line Voltage Sense	Connects to resistor divider for input OVP/brownout detection and sets minimum ZC count for high/low line adaptation.
3 CS	Current Sense Input	Receives primary-side shunt voltage for PWM off-time determination and cycle-by-cycle peak current limiting.
4 ZCD	Zero-Crossing Detection	Enables QR operation start-up, detects transformer demagnetization, and provides output OVP sensing path.
5–7 DRAIN	High-Voltage Drain Node	Direct connection to drain of integrated 700 V CoolMOS™; carries full primary switching current and voltage stress.
7 VCC	IC Supply Input	Power rail for controller core; regulated internally from ZCD during startup, with 10 V UVLO and 25.5 V OVP.
8 GND	Signal & Power Ground	Common reference for CS, FB, VIN, ZCD, and gate driver return; requires low-inductance layout to minimize noise coupling.

Key Features

Feature	Design Value
Integrated 700 V CoolMOS™	Eliminates external HV MOSFET and associated gate drive complexity while maintaining avalanche ruggedness for surge robustness.
Digital Frequency Reduction	Reduces switching frequency by up to 10 zero crossings under light load, improving efficiency and suppressing audible noise without analog tuning.
Enhanced Active Burst Mode	Allows user-selectable standby power entry/exit thresholds, enabling optimization between no-load consumption and wake-up latency.
Built-in Digital Soft Start	Controls PWM duty ramp-up via internal capacitor charging, preventing inrush current and transformer saturation during cold start.
Robust Line Protection	Dual-function VIN pin enables simultaneous brownout detection and input OVP with programmable hysteresis and auto-restart recovery.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quasi-resonant flyback controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ICE5QR1070AZ	Same silicon, identical R_DS(on), V_DS, and feature set; differs only in marking and packaging (no XKL suffix).	No functional difference; XKL denotes specific tape-and-reel configuration per Infineon's internal logistics code.	Select ICE5QR1070AZXKLA1 when requiring AEC-Q200-aligned traceability or specific reel size for automated assembly.
ICE5QR2270AZ	Higher R_DS(on) (2.13 Ω), lower output power (41 W @ 220 VAC), same 700 V rating and pinout.	Suitable for lower-power auxiliary supplies where thermal margin allows higher conduction loss.	Choose ICE5QR2270AZ only if design targets ≤41 W output and requires cost-optimized BOM without sacrificing package compatibility.

Compared with ICE5QR1070AZ and ICE5QR2270AZ, ICE5QR1070AZXKLA1 delivers highest power density (58 W) in DIP-7 with lowest R_DS(on), enabling smaller heatsinking and tighter layout in space-constrained consumer power supplies.

FAQ

What is the maximum continuous output power achievable with ICE5QR1070AZXKLA1?

The ICE5QR1070AZXKLA1 supports up to 58 W at 220 VAC ±20% and 32 W across universal 85–300 VAC input, based on open-frame thermal testing at T_a = 50°C and T_J = 125°C. Actual output depends on PCB copper area, heatsinking, and transformer design - Infineon recommends using their DER-712 reference design for validation.

How does the Active Burst Mode achieve <100 mW standby power?

Active Burst Mode reduces switching activity by gating the PWM signal based on feedback voltage level, with selectable entry/exit thresholds set via FB pin resistor network. Combined with digital frequency reduction and low quiescent current in controller core, it achieves <100 mW no-load consumption while maintaining fast wake-up response.

Can ICE5QR1070AZXKLA1 be used without an optocoupler for regulation?

No - the FB pin requires optocoupler feedback from secondary-side TL431 or equivalent shunt regulator to close the voltage loop. The IC does not support primary-side sensing or auxiliary winding regulation; FB pin functionality is strictly tied to optocoupler-coupled error amplification and burst control.

What is the purpose of the VIN pin beyond line protection?

The VIN pin sets the minimum zero-crossing count for digital frequency reduction, allowing distinct switching frequency profiles for high-line (220–240 VAC) and low-line (85–132 VAC) operation. This improves EMI performance and efficiency across the full input range without external programming components.
