Product Details
Description
LinkZero-AX is an integrated offline switching IC that enables designers to achieve 0.00 Watts of standby energy consumption in auxiliary power supplies. LinkZero-AX features an innovative power-down mode that effectively turns off the auxiliary power supply when the end product is idle or in standby. Power-down mode is triggered by a signal accessible to a microcontroller, completely shutting down internal switch control circuits. However, while in this power-down mode, the bypass pin remains regulated, allowing the LinkZero-AX IC to be awakened with a reset pulse or button press.
When paired with CapZero and SENZero, LinkZero-AX reduces standby power waste in high power products to as low as 5 mW, or effectively zero. Alternatively, while in power down mode, LinkZero-AX offers a simple means of providing up to 500uA at 4V from the regulated BYPASS pin. This current can be used to power a system wake up sensor while in power down mode while the rest of the system is in standby. This functionality, although increasing system standby power consumption, provides a simple means to power a low current sensor without requiring the power supply to switch.
Product Highlights
Lowest System Cost with Zero Standby Consumption
- Simple system configuration provides zero consumption standby/power down with user controlled wake up
- Very tight IC parameter tolerances improves system manufacturing yield
- Suitable for low-cost clampless designs
- Frequency jittering greatly reduces EMI filter cost
- Extended package creepage improves system field reliability
Advanced Protection/Safety Features
- Hysteretic thermal shutdown protection – automatic recovery reduces field returns
- Universal input range allows worldwide operation
- Auto-restart reduces delivered power by >85% during short-circuit and open loop fault conditions
- Simple ON/OFF control, no loop compensation needed
- High bandwidth provides fast turn on with no overshoot
EcoSmart – Energy Efficient
- Standby/power down consumption less than 3 mW at 230 VAC input*
- Easily meets all global energy efficiency regulations with no added components
- ON/OFF control provides constant efficiency to very light loads
Applications
- Ultra low consumption standby and auxiliary supplies
*IEC 62301 Clause 4.5 rounds standby power use below 5 mW to zero.
