• Planar transformer 60% thinner than traditional
• No electrolytic caps saves 40% PCB area
• Size: 82 x 39 x 10.5 mm = 34 cc (cased), ~62 x 35 x 8 mm = ~17 cc (PCBA)
• Efficiency DoE VI: 92% @ full load, 230 VAC
Legion 90W 2C
• High-frequency topology shrinks magnetics, EMI filter and output caps
• CrCM Boost PFC (150k-200 kHz) with NV6127 GaNFast power IC and NCP1622 controller
• HFQR DC-DC (130-160 kHz) with NV6125 and NCP1342
• Size: 66 x 63 x 28 mm = 116 cc (cased) = 0.8 W/cc
• 58 x 59.6 x 22 mm = 76 cc (PCBA) = 1.2 W/cc
• Efficiency DoE VI (90W, Dual Output):
• 91.8% @ full load, 230 VAC, 91.6% @ 130 VAC
