Product details

Overview

ICE3BR0680JZXKLA1 from Infineon Technologies is an integrated off-line SMPS current-mode controller with built-in 800V avalanche-rugged CoolMOS® and startup cell in PG-DIP-7 package. It delivers 82W at 230VAC ±15%, operates at a fixed 65kHz switching frequency with jitter, features active burst mode for <100mW standby power, and includes adjustable brownout, auto-restart protection, and propagation delay compensation. It targets auxiliary power supplies for PCs and servers.

For engineers reviewing the ICE3BR0680JZXKLA1 datasheet, ICE3BR0680JZXKLA1 pinout, ICE3BR0680JZXKLA1 application, or ICE3BR0680JZXKLA1 equivalent, key selection criteria include integrated 800V MOSFET voltage margin, selectable burst entry/exit thresholds, ±5% current limit tolerance, 50°C hysteresis overtemperature protection, and DIP-7 thermal performance without external heatsink.

Technical Context

The IC implements cycle-by-cycle current-mode control with patented propagation delay compensation for consistent peak power limiting across input line variations. Its BiCMOS process enables 10.5–25V VCC operation and low quiescent current during burst mode.

Brownout detection is externally adjustable via resistor dividers on the BBA pin, while burst mode entry/exit levels are set by FBB pin voltage thresholds. The integrated 800V CoolMOS® eliminates external high-voltage startup circuitry and supports direct rectified AC input connection.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	800V - Enables direct connection to 265VAC mains with safety margin for surge transients.
f_SW	65kHz fixed with jitter - Reduces EMI peaks and simplifies filter design vs. variable-frequency controllers.
R_DS(on)	0.62Ω @ 25°C - Limits conduction loss in 82W 230VAC adapter designs without forced cooling.
Standby Power	<100mW - Achieved via active burst mode, meeting Energy Star Level VI and EU CoC Tier 2 requirements.
Current Limit Tolerance	±5% - Ensures precise overcurrent protection across temperature and process variation.
Soft Start Time	10ms - Controls inrush current into bulk capacitor, reducing stress on rectifier and primary switch.
Blanking Time	20ms extendable - Prevents false OCP triggering during short-duration load surges (e.g., HDD spin-up).

Pinout & Package

Package: PG-DIP-7 (Plastic Dual In-line Package, 7-pin, 0.3" wide, creepage ≥5.0mm per IEC 60950-1).

Pin/Terminal	Circuit Role	Design Meaning
1 - BBA	Brownout / Blanking Extension / Auto-Restart Enable	Configurable brownout threshold; external capacitor extends blanking time; pull <0.4V to force auto-restart.
2 - FBB	Feedback Input / Burst Mode Control	Regulates output voltage; sets burst entry/exit power level via analog voltage threshold.
3 - CS	Current Sense Input	Monitors shunt voltage at CoolMOS® source for cycle-by-cycle current limiting and PWM modulation.
4 - n.c.	No Connect	Internally unconnected; must remain floating per datasheet.
5 - Drain	CoolMOS® Drain Terminal	High-side switch node connected directly to rectified AC input; rated for 800V blocking.
7 - VCC	Controller Supply	10.5–25V operating range; startup current limited to 0.9mA by internal cell.
8 - GND	Power & Signal Ground	Common reference for CS, FBB, BBA, and gate driver; requires low-inductance PCB layout.

Key Features

Feature	Design Value
Integrated 800V CoolMOS® with Startup Cell	Eliminates external HV startup resistor network and reduces component count by ≥3 parts in flyback adapters.
Active Burst Mode with Selectable Thresholds	Reduces standby power to <100mW while enabling user-defined transition points between continuous and burst operation.
Adjustable Brownout Protection	Prevents erratic regulation during brownout events by halting switching when input drops below programmable threshold.
Propagation Delay Compensation	Maintains ≤5% power limit variation between 85VAC and 265VAC inputs, improving design margin predictability.
Frequency Jittering + Soft Gate Drive	Reduces conducted EMI by spreading spectral energy and minimizing dv/dt-induced noise coupling.

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
ICE3BR1680JZ	Same PG-DIP-7 package and 800V CoolMOS®, but fixed 100kHz f_SW; no adjustable brownout; higher R_DS(on) (0.82Ω).	Optimized for higher-power (100W) adapters where EMI filtering favors higher frequency; less suitable for brownout-prone regions.	Select when higher switching frequency improves transformer size/cost and brownout immunity is secondary.
ICE5QSBG	650V CoolMOS®, 65kHz, Quasi-Resonant control; no integrated startup cell; requires external HV resistor.	Targeted at cost-sensitive DVD/STB designs with stable 230VAC input; lacks 800V surge margin and active burst mode.	Select only if input voltage stability is guaranteed and standby power >150mW is acceptable.

Compared with ICE3BR1680JZ and ICE5QSBG, ICE3BR0680JZXKLA1 uniquely combines 800V ruggedness, programmable brownout, and sub-100mW standby-making it optimal for globally deployed auxiliary supplies requiring universal input and regulatory compliance.

FAQ

What is the maximum continuous output power supported by ICE3BR0680JZXKLA1 at 230VAC?

The ICE3BR0680JZXKLA1 supports up to 82W continuous output power at 230VAC ±15% with Ta=50°C and no copper heatsink area. This rating assumes standard DIP-7 PCB layout with 2oz copper and minimal thermal relief. Derating is required above 50°C ambient or with reduced copper area.

How is the burst mode entry threshold configured?

The burst mode entry threshold is set by the DC voltage applied to the FBB pin: typical entry occurs at 1.25V and exit at 1.15V, both adjustable via external feedback divider. This dual-threshold hysteresis prevents oscillation near the transition point and enables fine-tuning of light-load efficiency versus output ripple.

Does ICE3BR0680JZXKLA1 require an external startup resistor?

No. The integrated startup cell provides 0.9mA constant-current charging of the VCC capacitor directly from the Drain pin, eliminating the need for an external high-voltage startup resistor and associated power loss. This feature enhances efficiency and reliability in universal-input designs.

What protection features are implemented with hardware-level response?

Hardware-level protections include overcurrent (CS pin threshold), VCC overvoltage (clamped at 27.5V), VCC undervoltage lockout (10.5V turn-off), overtemperature (150°C trip with 50°C hysteresis), and open-loop detection. All trigger immediate gate shutdown and enter auto-restart mode without software intervention.
