Typical Applications
ICE3RBR1765JGXUMA1 is suitable for 6 applications: 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.
Recommended
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.
Recommended
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.
Recommended
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.
Recommended
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.
Recommended
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.

Key Differentiators
- 650 V breakdown in PG-DSO-12-19 small-footprint package (vs ICE2QR2280GXUMA1)
- Active burst mode with frequency jitter integrated (vs ICE3PCS03GXUMA1)
- Same die available in tape-and-reel and bulk (vs ICE3RBR1765JG)
Design Notes
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.
