The XL7036 is a 150 kHz fixed‑frequency buck DC‑DC converter delivering up to 2.1 A with input up to 100 V.
The XL7036 buck DC‑DC converter operates from 12 V to 90 V input and provides a fixed 150 kHz switching frequency. It delivers up to 2.1 A output current, supports adjustable output voltage from 1.25 V to 20 V, and includes built‑in short‑circuit and current‑limit protection. Typical applications include e‑bike controller power supplies and telecom/networking equipment. Performance graphs show efficiencies up to 94 % at 24 V input and 15 V output, with a maximum duty cycle of 100 % and a minimum dropout of 0.5 V.
