DVSB2800D DC-DC Converter
A true military and avionics grade thick-film hybrid DC-DC power converter, the DVSB Series eliminates the need for custom converters or multiple converters to satisfy multiple output voltage needs in a mil/aero power system. With outputs 3.3V and 5V, the DVSB Series can power systems from a single module, saving board space, weight, and development cost while enhancing the system reliability.
Features:
- Dual low voltage outputs of 3.3V and 5V
- Wide input voltage range: 15 to 50 Volts with 80V transient per MIL-STD-704
- Up to 12.5 watts output power
- Full performance over -55°C to +125° C. military temperature range
- Minimal cross regulation resulting from VPT’s dual control loop design topology
- Fault tolerant magnetic feedback circuit
- Extreme reliability: no use of optoisolators
- Very low output noise: 40mV typical
- Host of circuit protection features
- Extremely low profile (.355 inches) and light weight (24/28g) hermetic package
- Fixed switching frequency
- Ensure excellent thermal performance and unit isolation by using with the thermal pad TP-007
Compliances and Certifications:
- Available qualified to MIL-PRF-38534 Class H, DLA SMD #5962-08207
- VPT’s in house legacy Class KL1 available
- Manufactured in an MIL-PRF-38534 Class H and Class K, and ISO9001 certified manufacturing facility
- MIL-STD-704A input voltage requirements
