Product details

Overview

ICE3AR0680VJZXKLA1 from Infineon Technologies is an integrated off-line SMPS current-mode controller with built-in 800V avalanche-rugged CoolMOS™, startup cell, input overvoltage protection (OVP), and frequency jittering - all in a PG-DIP-7 package. It delivers 52W at 85–265 VAC, operates at 100 kHz fixed switching frequency, and achieves <100 mW standby power via Active Burst Mode for adapter/charger and auxiliary power supply applications.

For engineers reviewing the ICE3AR0680VJZXKLA1 datasheet, ICE3AR0680VJZXKLA1 pinout, ICE3AR0680VJZXKLA1 application, or ICE3AR0680VJZXKLA1 equivalent, key selection considerations include its integrated 800V CoolMOS™, adjustable input OVP threshold, 10ms soft-start, ±5% current-limit tolerance, and DIP-7 thermal performance in universal-input AC/DC converters.

Technical Context

This device implements a current-mode PWM control architecture with patented propagation delay compensation and dual-mode blanking (fixed 20 ms + extendable via BV pin) to maintain stable peak-current regulation across load transients and burst-mode operation. The control unit integrates Auto Restart protection for overtemperature (50°C hysteresis), VCC OVP/UVLO, open-loop, and overload conditions.

The integrated 800V CoolMOS™ enables direct rectified-line connection without external HV startup resistors, while the dedicated BV pin simultaneously configures input OVP threshold and extends blanking time - eliminating need for external OVP dividers or blanking timing components in compact designs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	800 V - Enables direct connection to 270 VAC rectified input with robust avalanche margin.
f_SW	100 kHz (jittered) - Reduces EMI peaks via frequency modulation without requiring external oscillator components.
R_DS(on)	0.62 Ω @ 25°C - Supports up to 52W output at 85–265 VAC with minimal conduction loss in DIP-7 package.
I_Limit tolerance	±5% - Ensures precise, consistent maximum power limiting across temperature and unit-to-unit variation.
Soft Start	10 ms built-in - Prevents inrush current and output overshoot during power-up without external RC network.
Standby Power	<100 mW - Achieved via Active Burst Mode with selectable entry/exit thresholds for energy-efficient no-load operation.
OVP Threshold	Adjustable via BV pin resistor divider - Enables programmable line overvoltage shutdown (e.g., >280 VAC) for regional grid safety compliance.

Pinout & Package

Package: PG-DIP-7 (Plastic Dual In-line Package, 7-pin, wide-body, creepage-optimized for 800V isolation). Pin 6 is omitted (no pin); pin 4 is internally not connected.

Pin/Terminal	Circuit Role	Design Meaning
1 - BV	Input OVP sense & blanking extension	Configures line overvoltage shutdown threshold and extends leading-edge blanking duration during overload events.
2 - FBB	Feedback & burst mode control	Accepts optocoupler feedback signal and sets burst entry/exit level via external resistor to ground.
3 - CS	Current sense input / MOSFET source	Direct connection to CoolMOS™ source; senses primary-side current for cycle-by-cycle limiting and slope compensation.
4 - n.c.	No connection	Internally unconnected; must remain floating - no PCB trace or component allowed.
5 - Drain	CoolMOS™ high-voltage drain	Connects directly to rectified AC line (e.g., bulk capacitor positive); rated for 800V DC blocking.
7 - VCC	Controller supply voltage	Receives bias from internal startup cell; regulated to 14.5 V; powers internal logic and gate driver.
8 - GND	Controller ground reference	Common return for CS, FBB, and internal circuitry; must be low-inductance connection to source pad.

Key Features

Feature	Design Value
Integrated 800V CoolMOS™ + startup cell	Eliminates external HV startup resistor and discrete MOSFET, reducing BOM count and board space in universal-input flyback designs.
Active Burst Mode with selectable thresholds	Enables dynamic adjustment of burst entry/exit points to optimize light-load efficiency and output ripple trade-offs per application.
Propagation delay compensation	Maintains accurate current-sense timing across full load range and burst mode, preventing false overcurrent trips under transient conditions.
Adjustable input OVP via BV pin	Allows region-specific overvoltage shutdown (e.g., 275 VAC for EU, 305 VAC for Japan) using only two external resistors.
Frequency jittering + soft gate drive	Reduces conducted and radiated EMI by spreading spectral energy and minimizing dv/dt-induced noise on gate loop.

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar off-line SMPS controller with integrated HV MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ICE3AR0680JZ	Lacks input OVP; includes brownout detection and external protection enable pin.	Suitable where line undervoltage monitoring is required but OVP is handled externally or omitted.	Select when brownout response is critical and OVP is implemented upstream (e.g., relay-based cut-off).
ICE3BR0680JZ	Same DIP-7 package and 800V CoolMOS™, but adds bi-directional burst mode and enhanced EMI reduction features.	Better suited for ultra-low EMI consumer audio systems where radiated noise must meet CISPR 32 Class A limits.	Choose for next-gen designs needing improved burst-mode smoothness and tighter EMI margins without changing layout.

Compared with ICE3AR0680JZ and ICE3BR0680JZ, the ICE3AR0680VJZXKLA1 uniquely provides factory-configured input OVP without sacrificing Active Burst Mode or soft-start integrity - making it optimal for cost-sensitive, safety-certified adapters where OVP is mandatory and brownout is unnecessary.

FAQ

What is the purpose of the BV pin?

The BV pin serves dual functions: it sets the input overvoltage protection (OVP) threshold via an external resistor divider and extends the leading-edge blanking time during overload conditions. This eliminates the need for separate OVP sensing circuitry and improves transient immunity without adding components - a key enabler for compact, certified adapter designs.

Does ICE3AR0680VJZXKLA1 require an external startup resistor?

No. The device integrates a dedicated startup cell that draws current directly from the rectified AC line through the CoolMOS™ drain, charging the VCC capacitor without any external high-voltage resistor. This reduces power loss, improves reliability, and simplifies PCB layout compared to controllers requiring discrete HV startup networks.

How does Active Burst Mode reduce standby power?

Active Burst Mode dynamically disables switching cycles when output load falls below a user-defined threshold (set via FBB pin resistor), reducing average switching losses. Combined with 100 kHz jittering and soft gate drive, it achieves <100 mW no-load consumption while minimizing audible noise and output voltage ripple - critical for Energy Star and EU CoC Tier 2 compliance.

Can this IC operate down to -40°C?

Yes. The ICE3AR0680VJZXKLA1 is fully specified from -40°C to +125°C junction temperature. Its BiCMOS process ensures stable current-limit accuracy, reliable burst-mode entry/exit, and robust gate drive performance across this full range - validated for use in outdoor-rated white goods and industrial control enclosures.
