MAX1558ETB+T

The MAX1558ETB+T refers to Maxim’s MAX1558 high‑voltage buck regulator along with its Evaluation Tool Board (ETB) and tape‑and‑reel (T) packaging. The MAX1558 is a high‑efficiency, step‑down switching regulator with an integrated switch, designed to convert a higher DC input to a lower regulated output for automotive/industrial/battery-powered applications. Key features typically include a wide input range, adjustable output via external feedback resistors, PWM/current‑mode control, soft‑start, enable control, and protection such as current limit and thermal shutdown. The ETB provides a ready‑to‑use board to rapidly evaluate performance (efficiency, ripple, transient response, protections) before committing to a full design. The +T suffix denotes production packaging suitable for tape‑and‑reel supply. For exact specifications, pinout, and application circuits, refer to the MAX1558 datasheet and the ETB user guide.

8 pins. It is a boost (step-up) DC-DC converter (high-efficiency switching regulator) with an integrated switch, used to generate a higher output voltage from a lower input voltage. The ETB+T suffix indicates the package (and tape-and-reel).

Manufacturer: Maxim Integrated. It is an American semiconductor company that designs and manufactures analog and mixed-signal integrated circuits (notably power management, sensing, and signal-conditioning ICs). Maxim Integrated is now part of Analog Devices.

Applications of MAX1558ETB+T:
- Battery-powered portable electronics (cell phones, cameras, wearables) needing compact, efficient DC-DC regulation.
- LCD bias and display backlight supply circuits.
- USB-powered peripherals and general power-management subsystems.
- IoT/sensors and microcontroller boards requiring multiple regulated rails.
- Automotive and industrial handheld instruments needing rugged, space-saving PMU solutions.

Package type: TQFN with exposed pad (EP). ETB+T denotes the Pb-free Tape & Reel variant.
