The MAX5035 is a high-efficiency, high-voltage, step-down DC-DC converter from Texas Instruments. It operates from an input voltage of up to 76V and has a maximum output current of 1A.
The MAX5035 is a high‑efficiency, high‑voltage step‑down DC‑DC converter that operates from an input voltage up to 76 V and delivers up to 1 A output current. It uses an internal low‑resistance DMOS transistor, provides internal frequency compensation, and includes protection features such as undervoltage lockout, cycle‑by‑cycle current limit, hiccup mode short‑circuit protection, and thermal shutdown.
The device is offered in 8‑pin SO and 8‑pin PDIP packages, works over an industrial temperature range of 0 °C to +85 °C, and achieves up to 94 % efficiency. Fixed‑output versions (MAX5035A/B/C) provide 3.3 V, 5 V, or 12 V, while the MAX5035D version offers an adjustable output from 1.25 V to 13.2 V.
