DVWR2800T DC-DC Converter
VPT’s DVWR Series incorporates a dual topology with independent control loops to ensure excellent regulation, especially for a low voltage output.
Features:
- Up to 25W of output power
- Triple outputs of 3.3V/ ±12V and 3.3V/ ±15V
- Separate control loops for 3.3V main and auxiliaries, for minimal cross regulation
- Full performance over-55° C to +125° C military temperature range
- Wide input voltage range: 15 to 50 volts with 80V transient
- Fault tolerant magnetic feedback circuit
- Very low output noise
- Host of circuit protection features
- Extremely low profile (.415 inches) and light weight (54/58g) fully hermetic package
- Fixed switching frequency
- Ensure excellent thermal performance and unit isolation by using with the thermal pad TP-004
