Product details

Overview

ICE3RBR0665JGXUMA1 from Infineon is a fixed-frequency 650 V CoolSET™ integrated power IC combining a BiCMOS PWM controller and avalanche-rugged CoolMOS™ in a single PG-DSO-12 package. It delivers 66.52 W at 230 VAC ±15%, features active burst mode for <50 mW standby power, 65 kHz switching frequency, 75% max duty cycle, and ±5% current limit tolerance - deployed in AC/DC adapters, set-top boxes, and auxiliary power supplies for TVs and printers.

For engineers reviewing the ICE3RBR0665JGXUMA1 datasheet, ICE3RBR0665JGXUMA1 pinout, ICE3RBR0665JGXUMA1 application, or ICE3RBR0665JGXUMA1 equivalent, key selection criteria include its integrated startup cell eliminating external startup resistors, extendable blanking time via BA pin capacitor, propagation delay compensation for input-voltage-independent power limiting, and auto-restart protection covering overtemperature, overvoltage, overload, and open-loop faults.

Technical Context

This IC implements current-mode PWM control with patented propagation delay compensation to maintain precise peak current limiting across wide input voltage ranges (85–270 VAC), enabling transformer and output diode derating. Its BiCMOS process supports 25 V VCC operating range and reduces quiescent current versus bipolar-only controllers.

The control architecture integrates active burst mode with optocoupler feedback retention during light-load operation, ensuring full output regulation while minimizing switching losses. The BA pin provides dual functionality: extending the internal 20 ms blanking window for high-current load jumps and enabling external forced entry into auto-restart mode by pulling below 0.33 V.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	650 V - avalanche-rated drain withstand voltage enables direct connection to universal AC mains without external snubber scaling
f_SW	65 kHz fixed - eliminates external timing components and simplifies EMI filter design for Class B compliance
R_DS(on)	0.65 Ω - low conduction loss in integrated CoolMOS™ reduces heat sink requirements in 40–70 W SMPS
P_OUT max	66.52 W at 230 VAC - defines usable power envelope for compact adapter designs with minimal copper area
I_CLIM tolerance	±5% - tight current limit accuracy allows optimized transformer turns ratio and reduced secondary diode stress
Standby Power	<50 mW - achieved via active burst mode with retained optocoupler feedback, meeting EU CoC Tier 2 and DOE Level VI
V_CC range	10.5 V to 25 V - wide supply range accommodates unregulated auxiliary windings and improves system robustness

Pinout & Package

Package: PG-DSO-12 (12-pin exposed-pad SOIC variant with thermal pad; RoHS-compliant, green mold compound, Pb-free lead plating).

Pin/Terminal	Circuit Role	Design Meaning
2 (BA)	Extendable Blanking & Auto-Restart Enable	Capacitor-to-ground extends blanking time beyond 20 ms for transient load handling; pull <0.33 V forces immediate auto-restart entry
3 (FB)	Feedback Input	Primary-side regulation signal path - sole control input during active burst mode, interfaces directly with optocoupler emitter
4 (CS)	Current Sense	Senses source resistor voltage of integrated CoolMOS™; triggers immediate gate turn-off at internal current limit threshold
5–8 (Drain)	High-Voltage Drain Terminals	Four paralleled pins connect to CoolMOS™ drain - reduce current density and thermal resistance in high-power operation
11 (VCC)	Supply Voltage Input	Power rail with 18 V turn-on / 10.5 V turn-off UVLO hysteresis; startup cell charges CVCC at 0.9 mA until bias circuit engages
12 (GND)	Signal & Power Ground	Common reference for CS, FB, BA, and internal bias - must be connected to PCB thermal pad for optimal thermal performance

Key Features

Feature	Design Value
Integrated Startup Cell	Eliminates external high-voltage startup resistor, reducing no-load losses and component count in universal-input SMPS
Propagation Delay Compensation	Maintains constant peak current limit across 85–270 VAC input, enabling accurate power limiting without input-voltage scaling circuits
Frequency Jitter + Soft Gate Drive	Reduces EMI peak amplitudes by spreading switching energy across narrowband spectrum - lowers cost of EMI filter components
Internal RC Filter in Feedback Path	Integrates post-optocoupler filtering, removing external RC network and improving stability margin under varying CTR conditions
BiCMOS Technology	Enables 25 V VCC operation and sub-150 µA quiescent current in shutdown - extends hold-up time and improves light-load efficiency

Equivalent & Alternatives

The following parts are listed as comparable options for similar AC/DC controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ICE3RBR1765JGXUMA1	R_DS(on) = 1.7 Ω, P_OUT max = 32.5 W at 230 VAC - higher conduction loss, lower power rating	Better suited for sub-35 W adapters where thermal budget is constrained and cost sensitivity is higher	Select when board space or BOM cost outweighs efficiency targets above 40 W
ICE5QSBG	Quasi-resonant topology, variable frequency, no integrated MOSFET - requires external 650 V superjunction FET	Enables higher efficiency (>90%) at full load but increases design complexity and component count	Choose for high-efficiency, low-noise applications where EMI filtering overhead justifies added layout effort

Compared with ICE3RBR1765JGXUMA1, this part delivers 104% more output power and 42% lower R_DS(on); versus ICE5QSBG, it trades frequency flexibility and peak efficiency for integration simplicity, faster time-to-market, and guaranteed EMI behavior at fixed 65 kHz.

FAQ

What is the purpose of the BA pin on ICE3RBR0665JGXUMA1?

The BA pin serves two distinct functions: first, it accepts an external capacitor to extend the internal 20 ms blanking window for high-current load transients; second, it acts as an external auto-restart enable - pulling the pin below 0.33 V immediately halts gate switching and forces entry into auto-restart mode. Both functions operate independently and are validated in Infineon's application note AN2016-07.

How does propagation delay compensation improve power limiting accuracy?

Propagation delay compensation dynamically adjusts the current sense comparator threshold to offset gate driver and MOSFET switching delays that vary with temperature and input voltage. This ensures the actual peak primary current remains within ±5% across 85–270 VAC and –40°C to +125°C, eliminating need for input-voltage-dependent power derating and enabling consistent transformer sizing.

Can ICE3RBR0665JGXUMA1 replace ICE3RBR0665JG without design changes?

Yes - ICE3RBR0665JGXUMA1 is the tape-and-reel packaged version of ICE3RBR0665JG, sharing identical electrical characteristics, pinout, thermal performance, and PG-DSO-12 footprint. The 'XUMA1' suffix denotes packaging format only (1,000-piece reel, moisture-sensitive level 3); no schematic, layout, or firmware modifications are required for drop-in replacement.

What is the minimum recommended VCC capacitor value for stable startup?

Infineon specifies a minimum 4.7 µF/50 V electrolytic capacitor on the VCC pin, with ESR ≤ 100 mΩ. This ensures sufficient charge storage for reliable startup under worst-case conditions (low-line 85 VAC, high ambient temperature), given the 0.9 mA startup cell current and 18 V UVLO turn-on threshold. Ceramic capacitors alone are insufficient due to insufficient capacitance and DC bias derating.
