MAX660EPA+ DIP-8 Voltage Converter IC

MAX660EPA+ is a CMOS monolithic voltage converter in an 8-pin DIP package. This is a monolithic charge pump voltage inverter, converts +1.5V to +5.5V input to corresponding -1.5V to -5.5V output. Using only two low-cost capacitors, the charge pump's 100mA output replaces the switching regulator, eliminating inductors and the associated cost, size, and EMI. Greater than 90% efficiency over most of the load current range, combined with a typical operating current of only 120µA, provides ideal performance for both battery-powered and board-level voltage conversion applications. The MAX660 can also double the output voltage of an input power supply or battery, providing +9.35V at 100mA from a +5V input. A frequency control pin selects 10KHz type or 80KHz type (40KHz min) operation to optimize capacitor size and quiescent current. The oscillator frequency can also be adjusted with an external capacitor or driven by an external clock.
