Maxim MAX660CPA

比率充电泵1.5V5.5V100mA

Overview

The MAX660CPA 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.

♦ Small Capacitors ♦ 0.65V Typ Loss at 100mA Load ♦ Low 120µA Operating Current ♦ 6.5Ω Typ Output Impedance ♦ Guaranteed ROUT < 15Ω for C1 = C2 = 10µF ♦ Pin-Compatible High-Current ICL7660 Upgrade ♦ Inverts or Doubles Input Supply Voltage ♦ Selectable Oscillator Frequency: 10kHz/80kHz ♦ 88% Typ Conversion Efficiency at 100mA (IL to GND)
