The XLSEMI XL7005A datasheet provides specifications for a 0.4 A, 150 kHz, 100 V buck DC‑DC converter.
The XL7005A is a high‑efficiency, high‑voltage buck DC‑DC converter with a fixed 150 kHz switching frequency. It delivers up to 0.4 A output current, supports an adjustable output voltage from 1.25 V to 20 V, and offers up to 85 % efficiency.
Typical applications include electric‑vehicle controller power supplies and communication equipment. The device includes built‑in over‑temperature, over‑current, and short‑circuit protection, and is supplied in an SOP‑8 EP package. This manual is written in Chinese.
| Maximum input voltage | 100 V |
|---|---|
| Output voltage range | 1.25 V – 20 V (adjustable) |
| Maximum output current | 0.4 A |
| Switching frequency | 150 kHz (fixed) |
| Efficiency | up to 85 % |
| Maximum duty cycle | 90 % |
| Package | SOP‑8 EP |
The device can tolerate up to 100 V on its input.
The converter operates at a fixed 150 kHz; if the output shorts, the frequency drops to 45 kHz.
It includes over‑temperature shutdown, over‑current limiting, and output short‑circuit protection.
