TC7660SCPA Datasheet

Charge Pumps


The TC7660SCPA device is a pin-compatible replacement for the industry standard 7660 charge pump voltage converter. It converts a +1.5V to +12V input to a corresponding -1.5V to -12V output using only two low-cost capacitors, eliminating inductors and their associated cost, size and electromagnetic interference (EMI).Added features include an extended supply range to 12V, and a frequency boost pin for higher operating frequency,allowing the use of smaller external capacitors. TC7660SCPA Features • Oscillator boost from 10 kHz to 45 kHz• Converts +5V Logic Supply to ±5V System• Wide Input Voltage Range: +1.5V to +12V• Efficient Voltage Conversion (99.9%, typical)• Excellent Power Efficiency (98%, typical)• Low Power Consumption: 80 μA (typical) @ VIN = 5V• Low Cost and Easy to Use - Only Two External Capacitors Required• Available in 8-Pin Small Outline (SOIC) and 8-Pin PDIP Packages• Improved ESD Protection (10 kV HBM)• No External Diode Required for High-Voltage Operation
