The MAX1556 evaluation board (EV kit) is a fully assembled and tested circuit board for evaluating the PWM step-down DC-DC converters MAX1556 and MAX1557. The operating voltage of the board is 2.6V ~ 5.5V, and it features high efficiency, small size, and adjustable output voltage.
This Maxim datasheet describes the MAX1556 and MAX1557 step‑down DC‑DC regulators. It provides the selectable output voltages, maximum output currents, input voltage range, and pin‑configuration tables.
The document also includes recommended external components, shutdown control options, and example wiring diagrams to help designers integrate the regulators into their circuits.
| Output voltage (MAX1556) | 1.8V, 2.5V, 3.3V |
|---|---|
| Output voltage (MAX1557) | 1.0V, 1.3V, 1.5V |
| Maximum output current (MAX1557) | 600 mA |
| Input voltage range | 2.6 V – 5.5 V |
The MAX1556 can be set to 1.8 V, 2.5 V, or 3.3 V output.
The MAX1557 provides selectable outputs of 1.0 V, 1.3 V, or 1.5 V.
Both regulators operate with an input voltage between 2.6 V and 5.5 V.
