Diodes Incorporated has extended its family of dedicated active OR'ing MOSFET controllers with the ZXGD3112N7 designed for redundant power supply architectures up to 400 V in telecom, data center, and server duties. The ZXGD3112N7 is designed to fully enhance very low RDS(ON) power MOSFETs. This enables the replacement of a Schottky blocking diode which in turn lowers the operating temperature and increases system integrity. By driving MOSFETs as ‘ideal diodes’ the controller improves the overall system efficiency in high-voltage power systems.
Features
- Light load stability
- The typical -3 mV (±2 mV tolerance) turn-off threshold enables the control of very low RDS(on) MOSFETs while maintaining stability under light load conditions
- Fast turn-off
- 5 A current sinking capability allows fast-gate discharge of paralleled OR'ing MOSFETs and avoids reverse current flow under fault conditions
- Increased reliability and efficiency
- Increased efficiency eases the thermal design and reduces the heatsinking size and cost. Moreover, it lowers the operating temperature which increases the overall power system reliability
Applications
- Target application is OR'ing rectifiers in (N+1) redundancy power supply architectures up to 400 V for power rails found in:
- Telecoms
- Data centers
- Servers
