Maxim MAX660CSA

比率充电泵1.5V5.5V100mA

Overview

The MAX660CSA 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-costcapacitors, 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 MAX660CSA 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 (FC) pin selects either 10kHz typ or 80kHz typ (40kHz min) operation to optimize capacitor size and quiescent current. The oscillator frequency can also be adjusted with an external capacitor ordriven with an external clock. The MAX660CSA is a pin-compatible, high-current upgrade of the ICL7660. The MAX660CSA is available in both 8-pin DIP and small-outline packages in commercial, extended, and military temperature ranges. For 50mA applications, consider the MAX860/MAX861 pin-compatible devices (also available in ultra-small μMAX packages).
