Quasi-Resonant PWM Controller from Diodes Incorporated Optimizes Efficiency in Power Adapter Applications

Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic, analog and mixed-signal semiconductor markets, today introduced the AP3301. This quasi-resonant (QR) PWM controller enables the implementation of high-performance, cost-effective power supplies that are capable of meeting DOE6/COC Tier 2 efficiency requirements at all load levels. Targeting the key market of AC-DC adapters for set-top box and gaming console applications, this controller also meets the auxiliary power requirements of ATX/BTX computer motherboards and is suited for use in open-frame switching power supplies.

1A DC-DC Buck Converters from Diodes Incorporated Achieve High Efficiency Under Light-Load and Full-Load Conditions

Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic, analog and mixed-signal semiconductor markets, today announced the AP3401 and AP3428. These DC-DC step-down converters are capable of driving loads up to 1A with excellent line- and load regulation provided by a constant-frequency PWM control that requires no external compensation and so minimizes component count and material costs. Developed to meet the demands of set-top boxes, TVs, routers, Wi-Fi modules and security systems, these buck converters feature low power consumption and highly-efficient light-load operation.

Super Barrier Rectifier from Diodes Incorporated Optimized for Solid-State Retrofit MR16 LED Lamps

Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic, analog and mixed-signal semiconductor markets, today introduced the SBRT3M40P1. This Trench Super Barrier Rectifier (SBR®) has been optimized to deliver a low forward-voltage drop in a small form factor while maintaining low reverse-current leakage. This capability addresses requirements for input bridge rectifiers in solid-state lighting (SSL) applications focused on 12V AC LED retrofit lamps, which provide a more efficient and longer life alternative to popular MR16 halogen bulbs.
