Beschreibung
This reference design is a digitally controlled, compact 1-kW AC/DC power supply design for server power supply unit (PSU) and telecom rectifier applications. The highly efficient design supports two main power stages, including a front-end continuous conduction mode (CCM) totem-pole bridgeless power factor correction (PFC) stage. The PFC stage features LMG341x GaN FET with integrated driver to provide enhanced efficiency across a wide load range and meet 80 plus titanium requirements. The design also supports a half-bridge LLC isolated DC/DC stage to achieve a +12-V dc output at 1-kW. Two control cards use C2000™ Piccolo™ microcontrollers to control both power stages.
Eigenschaften
- 80 Plus Titanium efficiency, η=>95% @ 20%-100% load
- CCM GaN based totem pole bridgeless PFC stage with >99% peak efficiency, enabled by LMG341x GaN FET with integrated driver
- Half-bridge Si MOSFET LLC stage with >98% peak efficiency
- Fast load transient, Vo change within 300mV @ 2.5A/us slew rate
- Low iTHD, <10%@10% load, <5% @ 20% load, <2% @ >50% load
- Power density 41W/in3, 38-mm by 66-mm by 160-mm
Typische Anwendungen
- Industrial AC-DC
- Merchant telecom rectifiers / Merchant network & server PSU
