MicroPower Direct claims that these devices are specifically built for board-level power distribution necessitating automated assembly. The devices are designed in a compact package with high-performance features and a wide range of temperature tolerances.
VDC Inputs and Outputs
According to the manufacturer, there are 41 standard models in the 1W ML100E series. These models operate from 3.3, 5, 12, and 24 VDC inputs. They also provide outputs of 3.3, 5, 9, 12, 15, 24, ±5, ±9, ±12, ±15, or ±24 VDC.

The (PDF) ML100E series of DC-DC converters offer circuit protection have an input/output isolation of 1,500 VCD. These devices are said to operate with 85% efficiency and operate over a temperature range of -40°C to +105°C. It should also be noted that the devices are cooled by free-air convection and as such, no heat sink is needed.
The isolation of the DC-DC converters is rated at 1.5kV. MicroPower Direct claims that the MTBF of the ML100E series (per MIL HDBK 217F) is greater than 3.5 Mhours.
The ML100E series comes packed in a miniature SMT enclosure with an industry-standard pinout. All models are available on tape/reel for use with Pic-and-Place (P&Ps) automated machines.
The manufacturer has also assured that all models are RoHS compliant and EN 62368 approved. They meet the requirements for IPC/JEDEC reflow soldering as well.
