Product Introduction
Optimized for consumer applications concerned with audible noise elimination, this solution extends the advantages of transition mode—high efficiency with low-cost components—to higher power ratings than previously possible. By utilizing a Natural Interleaving technique, both channels operate as masters (that is, there is no slave channel) synchronized to the same frequency. This approach delivers inherently strong matching, faster responses, and ensures that each channel operates in transition mode.
Complete system-level protections feature input brownout, output over-voltage, open-loop, overload, soft-start, phase-fail detection, and thermal shutdown. The additional FailSafe over-voltage protection (OVP) feature protects against shorts to an intermediate voltage that, if undetected, could lead to catastrophic device failure.
Features
- Phase Management Capability
- FailSafe OVP with Dual Paths Prevents Output Over-Voltage Conditions Caused by Voltage-Sensing Failures

- Inrush Safe Current Limiting: Prevents MOSFET conduction during inrush Eliminates reverse recovery events in output rectifiers
- Improved Audible Noise Performance
- Soft Start on Overvoltage
- Integrated Brownout
- Improved Efficiency and Design Flexibility over Traditional, Single-Phase Continuous Conduction Mode (CCM)
- Input Filter and Output Capacitor Current Cancellation: Reduced current ripple for higher system reliability and smaller bulk capacitor
- Reduced EMI filter size
- Enables Use of Low-Cost Diodes without Extensive Snubber Circuitry
- Improved Light-Load Efficiency
- Improved Transient Response
- Complete System-Level Protection
- 1-A Source/1.8-A Sink Gate Drivers
Applications
