描述

The MAX856 evaluation kit (EV kit) is a fully assembled and tested surface-mount printed circuit board. It can also evaluate the MAX858 or the adjustable-output MAX857/MAX859.

The MAX856—MAX859 are CMOS, step-up, DC-DC switching regulators for small, low input voltage or battery-powered systems. The MAX856/MAX858 accept a positive input voltage between 0.8V and 6V and convert it to a higher, pin-selectable output voltage of 3.3V or 5V. The MAX857/MAX859 adjustable versions accept 0.8V to 6V input voltages and generate a higher, adjustable output voltage in the 2.7V to 6V range. Typical full-load efficiencies for the MAX856-MAX859 are greater than 85%.

A movable jumper on the EV kit selects either a 3.3V or 5.0V output voltage. Additional pads on the board's solder side accommodate resistors for the LBI/LBO low-battery detector or MAX857/MAX859 output adjustment.
