Thick-film technology supports multilayer wiring, allowing multiple circuit layers to be stacked vertically, significantly increasing circuit density. For DC-DC power modules, this means integrating all components—transformers, filter inductors, control chips, power switches—within a limited space. The LHP10 series module measures only 39.2mm × 23mm × 8.01mm, yet delivers 10W of output power and provides up to three independent voltage outputs, exemplifying the spatial advantages of thick-film technology.
10,910 m, marking the entry of China’s deep‑earth exploration into the era of 10,000‑meter wells. Bottom‑hole temperature increases linearly with depth – in ultra‑deep wells it can exceed 200 °C, and in areas with high geothermal gradients it can reach or even exceed 230 °C. This has directly driven the development and engineering application of 250 °C and even 275 °C high‑temperature power supplies. ZITN’s high‑temperature linear power supplies already cover a case temperature of 275 °C, and its high‑temperature DC‑DC modules reach 200 °C, providing power‑supply technology reserves for ultra‑deep exploration equipment. Looking ahead, as deep‑earth projects target deeper and hotter objectives, 300 °C‑class power supplies will become the next technological battleground.
When selecting a DC-DC power module, output power, output voltage, operating temperature range, and reliability grade are the first core factors to determine. The Z28 series quarter-brick modules from ZITN Power offer multiple models covering different power levels and output voltages, suitable for various application scenarios. Based on the series datasheet, this article provides a selection analysis from the two dimensions of power rating and operating temperature.
