描述

The MAX1747 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board that contains three charge-pump regulators. The first one is a high-current step-up DC-DC converter and is configured for a +5V output that provides up to 200mA of current. The other two charge pumps are low-current charge pumps that generate positive and negative voltages. A +3.0VDC to +3.6VDC source can be utilized to power the EV kit input.

The low-current negative charge-pump circuit is configured for a -7V output; the low-current positive charge-pump circuit is configured for a +12V output. Both circuits provide up to 20mA of current. The high-current step-up DC-DC converter or the EV kit's input source can be used to power either or both charge pumps.

The MAX1747 EV kit demonstrates an inductorless and low profile (1.1mm max) solution. Operation up to 1.23MHz allows the use of tiny surface-mount components and provides fast transient response.
