Evaluates: MAX1518 19-3456 Rev 0 10/04 MAX1518 Evaluation Kit General Description Features The MAX1518 evaluation kit (EV kit) is a fully assembled +4.5V to +5.5V Input Range and tested surface-mount circuit board that contains a Output Voltages step-up switching regulator, a positive charge pump postregulated by a high-voltage linear regulator, a neg- +13V Output at 650mA (VMAIN) ative charge pump postregulated by a high-voltage +25V Output at 10mA (VPOS) negative linear regulator, and five high-current opera- tional amplifiers. The step-up switching circuit is config- -8V Output at 15mA (VNEG) ured for a +13V output (VMAIN) and provides up to Adjustable Output Voltages (External Resistors) 650mA from a +4.5V to +5.5V DC supply voltage. The positive linear regulator is configured for a +25V 1.2MHz Switching Frequency output (VPOS) using two charge-pump stages provid- Five High-Performance Operational Amplifiers ing up to 10mA. The negative linear regulator is config- ured for a -8V output (VNEG) using a single charge- Low-Profile Surface-Mount Components pump stage providing up to 15mA. The DC input Fully Assembled and Tested 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 Ordering Information for the negative charge-pump input. PART TEMP RANGE IC PACKAGE The MAX1518 EV kit demonstrates low-quiescent cur- rent and high efficiency for maximum battery life. 32 TQFN MAX1518EVKIT 0C to +70C Operation at 1.2MHz allows the use of tiny surface- 5mm x 5mm mount components.
