The DVTR series is a high reliability hybrid DC-DC converter that operates over the full military temperature range without power derating. It features a radiation immune magnetic feedback circuit and operates at a fixed frequency of 475 kHz. The converters utilize undervoltage lockout circuitry to eliminate slow start-up problems. They are designed and manufactured in a facility qualified to ISO9001 and certified to MIL-PRF-38534 and MIL-STD-883.
The DVTR2800S Series are high‑reliability hybrid DC‑DC converters designed for operation over the full military temperature range (‑55 °C to +125 °C) with no power derating. They feature a radiation‑immune magnetic feedback circuit, fixed 475 kHz switching frequency, and built‑in undervoltage lockout to prevent slow start‑up.
The datasheet lists electrical specifications such as input voltage range, output power up to 40 W, isolation voltage of 500 V oc, and options for radiation‑hardened or custom versions. It also includes connection diagrams, output‑voltage trim instructions, ordering codes, and SMD drawing numbers.
| Continuous Input Voltage | 15‑50 V |
