Product Details
| General Description The MAX660 monolithic, charge-pump voltage inverter converts a +1.5V to +5.5V input to a corresponding -1.5V to -5.5V output. Using only two low-cost capacitors, the charge pump’s 100mA output replaces switching regulators, eliminating inductors and their associated cost, size, and EMI. Greater than 90 efficiency over most of its 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. Features ● Small Capacitors ● 0.65V Typ Loss at 100mA Load ● Low 120µA Operating Current ● 6.5Ω Typ Output Impedance ● Guaranteed ROUT < 15W for C1 = C2 = 10mF ● Pin-Compatible High-Current ICL7660 Upgrade ● Inverts or Doubles Input Supply Voltage ● Selectable Oscillator Frequency: 10kHz/80kHz ● 88Typ Conversion Efficiency at 100mA (IL to GND) |
