ICE3BR0680JZ Présentation
An SMPS current-mode controller is a power-supply integrated circuit that regulates the output of a switched-mode power supply by sampling both output voltage error and primary-side peak current each switching cycle, then commanding an internal power MOSFET. It belongs to the broader hierarchy of AC-DC converters, flyback controllers, and integrated power management ICs used in offline power designs. This category enables compact isolated power conversion for white goods, adapters, and auxiliary supplies.
Key features of the ICE3BR0680JZ include an input brownout detection pin (BBA), active burst mode operation for standby power below 100 mW, extendable blanking time for overload protection, and an external auto-restart enable path. The active burst mode reduces no-load consumption to extremely low standby levels. Internal protection features include overcurrent, overvoltage, overtemperature, and open-loop detection with auto-restart behavior.
Typical applications include 40 W isolated flyback adapters, white-goods auxiliary power supplies, DVD/STB standby rails, and industrial low-power offline converters. The wide 800 V drain rating allows universal-mains operation (85-265 VAC) without additional input protection components. Internal current-mode control simplifies loop compensation and provides inherent cycle-by-cycle current limiting.
When designing with this device, ensure the VCC reservoir capacitor and BBA blanking-time network values are selected per Infineon application notes. The PG-DIP-7 package provides 7 through-hole pins suitable for wave or hand soldering and allows isolated creepage/clearance per safety standards.

Applications typiques
ICE3BR0680JZ convient pour 6 applications: 40W Universal-Mains Flyback Adapter, White-Goods Auxiliary Power Supply, Standby Power for DVD/STB/TV, Industrial Low-Power Offline Converter, LED Driver Auxiliary Supply, Battery Charger for Power Tools.
40W Universal-Mains Flyback Adapter
The ICE3BR0680JZ fits 40 W universal-mains (85-265 VAC) flyback adapters because it integrates an 800 V avalanche-rugged CoolMOS that withstands rectified mains peaks up to 375 VDC with substantial transient margin. Its 65 kHz fixed-frequency current-mode control simplifies loop compensation, while the 15.75 A peak current capability delivers 40 W continuous output on a 12-20 V rail. Active burst mode operation pulls standby power below 100 mW for Energy Star and CoC Tier-2 compliance, and the integrated startup cell eliminates external bootstrap components. The PG-DIP-7 through-hole package supports wave soldering and high isolation creepage for reinforced insulation per IEC 60950, making it a compact solution for travel adapters and white-goods wall-warts.
Recommandé
White-Goods Auxiliary Power Supply
The ICE3BR0680JZ is well suited for white-goods auxiliary supplies (refrigerators, washing machines, dishwashers) that require isolated low-power rails (5-24 VDC) for control boards and displays. Its 800 V MOSFET breakdown voltage tolerates harsh mains transients common in motor-driven appliances, while the 40 W output headroom supports auxiliary rails plus relay and indicator loads. Brownout detection via the BBA pin disables switching at low mains voltage, protecting the converter from undervoltage stress. The PG-DIP-7 package withstands high humidity and thermal cycling typical of appliance environments, and the fixed-frequency operation simplifies EMI compliance for CE-marked household products.

Standby Power for DVD/STB/TV
The ICE3BR0680JZ is ideal for standby power rails in DVD players, set-top boxes, and televisions where an isolated auxiliary supply keeps the system alive in standby mode. Its active burst mode pulls standby consumption below 100 mW, satisfying the strictest standby regulations while maintaining fast wake-up response. The integrated 800 V CoolMOS handles universal-mains operation without external switch components, and the current-mode control provides inherent cycle-by-cycle overcurrent protection for fault tolerance. The PG-DIP-7 footprint fits compact standby modules behind the main PCB, and the 40 W power capability supports auxiliary rails plus USB charging outputs.
Recommandé
Industrial Low-Power Offline Converter
The ICE3BR0680JZ suits industrial low-power offline converters (sensors, controllers, IoT gateways) requiring isolated 5-24 V rails from 85-265 VAC mains. The 800 V MOSFET breakdown provides robust operation against industrial mains transients and surge events, while the integrated protection features (overcurrent, overvoltage, overtemperature, open-loop detection with auto-restart) eliminate external supervisor circuitry. The 65 kHz switching frequency balances transformer size and EMI filter design, and the PG-DIP-7 package supports the through-hole construction preferred for industrial modules. Active burst mode reduces standby power for energy-conscious industrial installations.
Recommandé
LED Driver Auxiliary Supply
The ICE3BR0680JZ works well in LED driver auxiliary rails that need isolated low-voltage supply for driver control ICs and fan/cooling subsystems. Its 800 V CoolMOS tolerates the high DC bus voltage present in LED PFC front-end designs, and the integrated current-mode control provides fast transient response for LED dimming events. The 40 W power capability supports main LED driver boards up to mid-power fixtures (commercial downlights, panel lights). Active burst mode enables standby dimming modes below 100 mW, and the PG-DIP-7 package provides the isolation creepage required for safety-certified LED luminaires per IEC 61347.
Recommandé
Battery Charger for Power Tools
The ICE3BR0680JZ is well suited for cordless power-tool battery chargers that need isolated flyback conversion from universal mains to charge 12-40 V battery packs. Its 800 V MOSFET withstands mains transients common in workshop environments, while the 40 W power capability supports 1-2 A charging current for typical Li-ion packs. The integrated current-mode control provides accurate current limiting for CC/CV charge profiles, and active burst mode reduces no-load consumption when the battery is fully charged. The PG-DIP-7 package withstands the mechanical shock and thermal cycling of portable charger housings.

Notes de conception
Estimated: At full 40 W output on a 12 V rail from 230 VAC mains, primary-side conduction losses in the integrated 800 V CoolMOS (RDS(on) 0.71 Ω) at 65 kHz with ~30% duty cycle produce approximately 0.5-1 W dissipation in the MOSFET. The PG-DIP-7 package has theta_JA around 80 C/W (typical through-hole with no heatsink), so junction temperature rise is roughly 40-80 C above ambient. For 40 W continuous operation in enclosed adapters, ensure adequate PCB copper area on the drain tab (pin 5) for thermal spreading. Operating at 85 VAC worst-case mains increases MOSFET RMS current by ~30%, raising dissipation proportionally.
Place the VCC reservoir capacitor (typically 47-100 uF electrolytic plus 100 nF ceramic) as close as possible to pins 1 and 7 to minimize switching noise on the supply rail. The current-sense resistor at pin 4 should be a low-inductance type (e.g., wirewound or thick-film SMD with Kelvin connection) to prevent false triggering during the leading-edge current spike. Keep the FB optocoupler trace short and away from the drain switching node to avoid noise coupling. The BBA pin (pin 6) blanking-time network should be referenced to clean ground near pin 2.
Do not exceed the 800 V drain breakdown voltage by ensuring sufficient margin for mains transients and transformer leakage inductance spikes - a small RC snubber (typically 100 Ω + 470 pF) across the primary winding is recommended. The active burst mode entry/exit thresholds must be configured properly via the FB divider to prevent audible noise during light-load transitions. Ensure the VCC startup current (typically 1.5 mA at startup) does not overload the auxiliary winding during initial power-on. Do not omit the gate drive bypass network on VCC; inadequate bypassing causes erratic switching behavior.
