Typical Applications
ICE3AR1080JGXUMA1 is suitable for 6 applications: Smartphone and Tablet Chargers, White Goods Auxiliary Power Supply, Set-Top Box and Streaming Device Standby Supply, Industrial Auxiliary and Metering Power Supplies, LED Lighting Drivers (Non-Dimmable), Home Appliance Standby Power.
Smartphone and Tablet Chargers
The ICE3AR1080JGXUMA1 is well-suited to 10-20 W smartphone and tablet charger designs operating from universal 85-265 VAC mains. The integrated 800 V CoolMOS tolerates wide-range line transients, while the 100 kHz switching frequency keeps the transformer compact - typically an EE16 or EE19 core suffices for a 15 W design. Active burst mode drops standby power below 100 mW, satisfying EU CoC Tier 2 and DoE Level VI efficiency limits, and the built-in brownout feature prevents saturation at low-line brownout conditions. Designers place a 1 nF Y-capacitor on the primary side and use a TL431 plus optocoupler for secondary-side regulation.
Recommended
White Goods Auxiliary Power Supply
The ICE3AR1080JGXUMA1's 800 V MOSFET rating and rugged protection suite make it a strong choice for auxiliary SMPS in white goods such as refrigerators, washing machines, and dishwashers. These applications demand high reliability under harsh line conditions including surges, dropouts, and brownouts. The integrated brownout detection prevents transformer saturation during low-line events, while auto-restart fault handling recovers gracefully from overload or short-circuit conditions. A typical 12 V/1 A or 5 V/2 A auxiliary rail can be implemented with a single EE19 transformer and minimal external components. The PG-DSO-12-19 package's exposed thermal pad simplifies heatsinking through the PCB copper pour.
Recommended
Set-Top Box and Streaming Device Standby Supply
Set-top boxes, streaming sticks, and home gateways require a small standby converter that runs continuously to power the IR receiver, network interface, and wake-up logic. The ICE3AR1080JGXUMA1's active burst mode keeps standby power below 100 mW even with a 5 V/100 mA output, satisfying the EU 2019/1782 standby regulation. The 100 kHz fixed frequency allows a small EE13 transformer, and the auto-restart protection handles output short-circuits without latch-up - critical for always-on consumer electronics. Designers typically use a 3.3 V LDO post-regulator on the secondary side to feed the host processor's standby rail.
Recommended
Industrial Auxiliary and Metering Power Supplies
Industrial metering, IoT gateways, and PLCs often require an isolated 5 V, 12 V, or 24 V auxiliary rail sourced directly from 110/220 VAC mains. The ICE3AR1080JGXUMA1's 800 V MOSFET provides safety margin in industrial environments with poor power quality, and its -40C to +150C junction temperature range covers most indoor and outdoor enclosure conditions. The integrated current-mode control with cycle-by-cycle peak-current limiting protects the transformer and output rectifier from sustained overcurrent events. A typical 24 V/0.5 A design uses an EE25 transformer and a 1 A secondary Schottky diode, achieving >85% efficiency at full load.
Recommended
LED Lighting Drivers (Non-Dimmable)
Non-dimmable LED retrofit lamps and downlights in the 5-15 W range can use the ICE3AR1080JGXUMA1 as a constant-current flyback controller. The fixed 100 kHz operation keeps EMI within EN 55015 class B limits when combined with a small common-mode choke, and the active burst mode eliminates the need for complex PWM-dimming circuitry. By sensing output current through a primary-side reference design (using an auxiliary winding and a resistor divider into the FB pin), the converter maintains constant LED current over varying input voltage and LED forward voltage. Thermal performance is excellent because the exposed pad of the PG-DSO-12-19 dissipates directly into the PCB copper.
Recommended
Home Appliance Standby Power
Microwave ovens, coffee machines, and air conditioners require a small standby converter that powers the clock, display, and control panel even when the main load is off. The ICE3AR1080JGXUMA1's active burst mode keeps continuous standby losses below 50 mW, satisfying modern energy-efficiency standards. The built-in protections - overload, over-temperature, open-loop, and VCC under-voltage lockout - prevent damage during fault conditions common in appliance environments, such as fan failure causing elevated ambient temperature. A simple 5 V/0.5 A design fits on a 25 mm x 35 mm PCB and meets IEC 60335 safety requirements for household appliances.

Key Differentiators
- 800 V CoolMOS breakdown voltage for universal-mains designs (vs ICE3BR0680JGXUMA1 (650 V CoolSET-F3R))
- Integrated 800 V MOSFET eliminates external switch and gate driver (vs Discrete PWM controller + external MOSFET approach)
- Brownout protection prevents transformer saturation (vs Older CoolSET-F2 (no brownout) variants)
- Active burst mode achieves <100 mW standby power (vs Fixed-frequency PWM controllers without burst mode)
Design Notes
Estimated: At a 15 W continuous output on universal mains (VIN average 265 VAC, VOUT 12 V, IOUT 1.25 A), the integrated CoolMOS dissipates roughly 0.7-1.0 W. The PG-DSO-12-19 package has a junction-to-ambient thermal resistance of approximately 95 C/W on a 1 square inch single-sided copper pour (per Infineon CoolSET-F3R80 datasheet thermal tables). With 1 W dissipation, the junction rises about 95 C above ambient, so derate to 0.7 W maximum on a minimal copper footprint, or use a 2 square inch pour to keep Tj below 110 C at 50 C ambient. Forced-air cooling extends power capability further.
Keep the current-sense (CS) trace short and direct - route it from the sense resistor to the CS pin without crossing any switching node. Place the VCC decoupling capacitor (typically 22 uF electrolytic in parallel with 100 nF ceramic) within 5 mm of the VCC pin to suppress supply pumping during MOSFET turn-off. The drain snubber (typically 100 pF to 1 nF high-voltage ceramic in series with a 10-100 k resistor) should be placed directly across the DRAIN pin and the transformer's primary return, with the loop area minimized to reduce conducted and radiated EMI.
Do not exceed the VCC maximum voltage of 25 V - during startup and at high line, the auxiliary winding voltage can overshoot if the VCC clamp is undersized. Use a 25 V or higher Zener diode in parallel with the VCC capacitor to clamp transients. The FB pin should see no more than 4.5 V; verify the optocoupler CTR and resistor divider to keep the FB voltage in the 2-4 V typical operating range. The CS pin must be bypassed with a 1 nF ceramic to ground to filter high-frequency noise that can cause false triggering.
The built-in frequency jitter helps meet EN 55022 / EN 55015 conducted EMI limits but is not a substitute for a proper input filter. Use a 10-22 uF X2 capacitor across the line input and a 10-33 mH common-mode choke on the AC input, plus a 2.2 nF Y1 capacitor from primary to secondary ground (for isolated designs) to attenuate common-mode noise. Place the common-mode choke upstream of the bridge rectifier. For conducted emissions below 2 MHz, the jitter spectrum spreading combined with a pi-filter (CLC topology) typically achieves >6 dB margin below the Class B limit.
