The MAX1518 evaluation kit (EV kit) is a fully assembled

and tested surface-mount circuit board that contains a

step-up switching regulator, a positive charge pump

postregulated by a high-voltage linear regulator, a neg-

ative charge pump postregulated by a high-voltage

negative linear regulator, and five high-current opera-

tional amplifiers. The step-up switching circuit is config-

ured for a +13V output (VMAIN) and provides up to

650mA from a +4.5V to +5.5V DC supply voltage.

The positive linear regulator is configured for a +25V

output (VPOS) using two charge-pump stages provid-

ing up to 10mA. The negative linear regulator is config-

ured for a -8V output (VNEG) using a single charge-

pump stage providing up to 15mA. The DC input

source or the step-up switching regulator output pro-

vides power for the positive charge-pump input. The

DC input source or the power ground provides power

for the negative charge-pump input.

The MAX1518 EV kit demonstrates low-quiescent cur-

rent and high efficiency for maximum battery life.

Operation at 1.2MHz allows the use of tiny surface-

mount components.
