ICE3RBR1765JGXUMA1 - 650V Offline Flyback CoolSET | Infineon
MPN: ICE3RBR1765JGXUMA1 ✓ نشطICE3RBR1765JGXUMA1 نظرة عامة
An AC-DC offline switching converter is a power-management IC that converts rectified AC mains (typically 85-265 VAC) into one or more regulated DC output rails using a flyback transformer topology. The CoolSET family from Infineon integrates the high-voltage power switch, current-sense controller, and protection logic into a single monolithic device, replacing discrete implementations that require separate PWM controllers and external MOSFETs. Within the broader power-management hierarchy, the CoolSET sits between primary-side controllers and fully integrated modules (DC-DC converters), targeting low-to-medium-power SMPS designs.
Key features include BiCMOS technology with active burst mode for ultra-low standby power (well below 100 mW), built-in frequency jitter to ease EMI compliance, soft gate driving to limit switching losses, propagation-delay compensation for accurate duty-cycle control, built-in soft-start, and extendable blanking time for overload protection. An external auto-restart enable pin provides flexible fault recovery. These integrated features reduce external BOM count by typically 15-20 components versus discrete implementations.
The device uses a BiCMOS process node optimized for high-voltage switching, pairing a 650V-rated MOSFET drain with low-power CMOS control logic. Current-mode control provides inherent cycle-by-cycle current limiting and simplified feedback loop compensation compared to voltage-mode control. Frequency jitter spreads switching noise spectrum to ease conducted EMI filtering requirements.
Typical applications include auxiliary supplies for white goods and home appliances, standby power for TVs and set-top boxes, low-power adapters, and industrial control board housekeeping rails. The active burst mode enables energy-star compliance with standby power typically below 100 mW.
When designing, ensure adequate Vcc hold-up capacitance to ride through short mains dropouts and verify transformer leakage inductance is below 5% of primary inductance to prevent avalanche stress on the integrated 650V MOSFET.

التطبيقات النموذجية
ICE3RBR1765JGXUMA1 مناسب لـ 6 التطبيقs: White Goods Auxiliary SMPS, TV and Set-Top Box Standby Rail, Low-Power AC Adapter (5-15 W), Industrial Control Board Housekeeping, LED Driver Auxiliary Power, Smart Home / IoT Gateway Power.
White Goods Auxiliary SMPS
Auxiliary power supplies in washing machines, refrigerators, and dishwashers demand standby power below 100 mW to meet Energy Star and EU Ecodesign regulations. The ICE3RBR1765JGXUMA1's active burst mode achieves standby consumption in the 50-80 mW range, while the 650 V breakdown rating handles universal 85-265 VAC mains without additional clamping. Its 65 kHz switching with built-in frequency jitter eases EMI compliance in cost-sensitive appliance layouts.

TV and Set-Top Box Standby Rail
Modern televisions and set-top boxes require a continuously-on 5V standby rail to power IR receivers, network interfaces, and main MCU wake circuits, all while drawing less than 100 mW at no-load. The ICE3RBR1765JGXUMA1's active burst mode and 75% maximum duty cycle support 5V/100 mA standby designs with high efficiency across the full universal-mains range. Soft-start and extendable blanking protect against transformer saturation during power-up.

Low-Power AC Adapter (5-15 W)
Universal-mains adapters for IoT gateways, modems, and small appliances benefit from the ICE3RBR1765JGXUMA1's integrated 650V MOSFET, current-mode control, and BiCMOS process. The 10.5-25 V Vcc range supports wide-input flyback designs with simple single-winding Vcc generation. Frequency jitter reduces conducted EMI by 5-7 dB, often eliminating one common-mode filter stage versus fixed-frequency controllers.
موصى به
Industrial Control Board Housekeeping
Industrial PLCs and motor-drive control boards require isolated housekeeping supplies that operate reliably across wide mains variations including 3-phase industrial 400-480 VAC rectified inputs. The ICE3RBR1765JGXUMA1's 650 V breakdown withstands rectified 480 VAC peaks (approximately 680 V) with appropriate derating, while current-mode control and auto-restart protection handle fault conditions in unattended industrial environments.
موصى به
LED Driver Auxiliary Power
Isolated flyback LED drivers in commercial luminaires often integrate a housekeeping rail powered by a CoolSET. The ICE3RBR1765JGXUMA1 supports isolated 5-12 V auxiliary outputs that power MCU and wireless-control circuitry in dimmable luminaires. Active burst mode keeps standby below 100 mW when lights are off, critical for emergency-lighting and building-automation compliance.
موصى به
Smart Home / IoT Gateway Power
Always-on smart-home hubs and IoT gateways draw 1-3 W continuously and benefit from the ICE3RBR1765JGXUMA1's low standby power. The integrated 650 V MOSFET eliminates external switching transistors, reducing PCB area to typically 25x35 mm. Frequency jitter allows cost-effective EMI filtering with a single common-mode choke plus Y-capacitor network, achieving EN 55022 Class B compliance.

ملاحظات التصميم
Estimated: at full 15 W output from a universal-mains flyback, the integrated 650 V MOSFET dissipates approximately 0.5-0.8 W (switching + conduction). With PG-DSO-12-19 theta_JA of approximately 80 C/W on a 1 oz 1 square-inch copper pour, junction rise is 40-64 C above ambient - acceptable up to about 85 C ambient. Above 85 C ambient or 20 W output, add thermal vias under the exposed pad and increase copper area to 2-3 square inches.
Keep the drain trace (pin 1) short and wide; the high dv/dt node injects common-mode noise into adjacent traces. Place the Vcc hold-up capacitor within 5 mm of pins 2-3, the CS resistor within 3 mm of pin 5, and the FB optocoupler ground return directly to pin 7 (GND) using a separate trace that does not share the power ground return. A 4-layer PCB with continuous ground plane below the IC is strongly recommended for EMI margin.
Do not exceed the 25 V Vcc maximum, even briefly, during load-dump transients - add a 27 V Zener clamp from Vcc to GND. Ensure transformer leakage inductance is below 5% of primary inductance to prevent avalanche stress on the integrated MOSFET; a small RC snubber (typically 100 ohm + 100 pF) across the primary winding is recommended for designs with poor coupling.
The auto-restart enable pin (pin 6) sets fault-recovery behavior via an external resistor divider. Tie to GND for latch-off, or to a defined voltage for auto-restart after fault. The FB pin (pin 4) requires a 1-10 nF compensation capacitor to GND - do not omit this part as it sets loop bandwidth and burst-mode entry threshold.
