What are the key features of ICE3AR0680JZ?

Current-mode PWM control with active burst mode for high light-load efficiency in offline supplies
11.2 V to 25 V VCC operating range compatible with standard flyback auxiliary winding designs
Integrated green-mode operation reduces standby power consumption below regulatory limits
7-pin DIP-7 package enables easy prototyping and low-cost through-hole PCB assembly

What is ICE3AR0680JZ used for?

The ICE3AR0680JZ is primarily used in offline flyback converters for AC/DC power adapters serving consumer electronics such as set-top boxes, routers, and smart home devices. Its green-mode burst operation allows standby power consumption to meet stringent international energy-efficiency regulations, including ErP Lot 6 and ENERGY STAR standards. It is also applied in auxiliary power supply stages of larger inverters and industrial power modules where a self-powered 17 V VCC rail drives the controller.

Frequently Asked Questions

What control method does the ICE3AR0680JZ use, and how does burst mode reduce standby losses?

The ICE3AR0680JZ employs current-mode pulse-width modulation (PWM) as its primary control method, with an integrated green-mode burst function that skips switching pulses under light-load conditions. By entering burst mode at loads below a threshold corresponding to roughly 11.2 V VCC minimum, the controller reduces switching frequency dramatically, cutting switching and gate-drive losses to keep standby consumption well under 1 W.

In which offline converter topologies is the ICE3AR0680JZ most commonly used?

The ICE3AR0680JZ is predominantly used in single-switch flyback converter designs operating from 85 V to 264 V AC mains, where the auxiliary winding provides the 11.2 V to 25 V VCC supply to the controller. The 7-pin DIP footprint and internal slope compensation make it a straightforward drop-in for cost-sensitive AC/DC adapters rated from a few watts to approximately 65 W output power.

What input voltage range does the ICE3AR0680JZ require, and how is this supply typically generated on the PCB?

The ICE3AR0680JZ requires a VCC supply between 11.2 V minimum and 25 V maximum, with a nominal 17 V target. In a flyback converter, this voltage is generated by an auxiliary winding on the transformer and a rectifier-capacitor circuit, allowing the controller to power itself from the same magnetic core that drives the output. A startup resistor from the high-voltage DC bus charges the VCC capacitor during cold start before the auxiliary winding takes over.

How does the ICE3AR0680JZ compare to an 8-pin DIP PWM controller such as the UC3842 for a compact charger design?

Compared to the classic 8-pin UC3842, the ICE3AR0680JZ in a 7-pin DIP package integrates green-mode burst functionality and optimized soft-start circuitry that the UC3842 lacks natively, reducing external component count by 2 to 4 passives in a charger design. Both use current-mode PWM control with similar 1 MHz maximum switching frequency capability, but the ICE3AR0680JZ's built-in light-load efficiency features help modern chargers meet sub-30 mW no-load power requirements without additional circuitry.
