HTD1R5B-1200D DC-DC Converter
The HTD Series of high temperature DC-DC converters is specifically designed for extreme temperature environments.
Hybrid microcircuit technology provides superior reliability in high temperature applications. Bare semiconductor die are integrated with passive components using thick film conductors on a ceramic substrate. A hermetic metal package protects internal components for long term reliability.
The HTD1R5B Series utilizes a boundary mode, peak current controlled flyback topology with primary side regulation. The flyback topology achieves high efficiency at low power levels, over a wide input voltage range.
High temperature performance is guaranteed through qualification, component lot testing and analysis. The HTD Series has been characterized over the full operating temperature range from -55 °C to +155 °C, including electrical performance, operating life, temperature cycling, mechanical shock and vibration.
The HTD Series is intended for harsh environments including down-hole oil and gas, MWD/LWD and wireline logging tools, aircraft engine electronics, and other industrial applications.
