The MAX5038/MAX5041 are dual-phase PWM controllers that provide high output-current capability in a compact package with a minimum number of external components
The MAX5038 and MAX5041 are dual‑phase, average‑current‑mode PWM controllers that provide high‑output‑current capability in a compact SSOP package. They support input voltages of +4.75 V to +5.5 V or +8 V to +28 V and can operate without external heatsinks thanks to low Rds(on) MOSFETs.
Key features include differential remote‑sense output, internal voltage regulator, selectable fixed or adjustable output voltages, clock input/output for synchronization, and built‑in thermal protection. Typical applications are servers, workstations, high‑density point‑of‑load regulators, networking systems, and high‑end desktop computers.
