BOLERO HV DC/DC CONVERTERS
48V Input – 52VDC – 4A Output
GPBW52V04 – ¹/2 Brick Bolero HV Series
• Industry standard pinout and footprint
• Highest efficiency in the industry: 92% at 52V, 4A; 91% at 52V, 2A
• No heat sink required (baseplate standard)
• Very low common-mode noise for a commercial DC/DC converter
• Two-stage input filter
• Constant switching frequency, 330 kHz
• Remote sense
• Single board SMT construction
• Low profile, 0.43"
• Optional low profile heat sink or baseplate for improved thermal performance
• Header with M3 metal inserts for mechanical connection to PCB
