TC7660 IC - Charge Pump DC to DC Voltage Converter IC

The TC7660 device is a pin-compatible replacement for the industry standard 7660 charge pump voltage converter. It converts a 1.5V to 10V input to a corresponding -1.5V to -10V output using only two low-cost capacitors, eliminating inductors and their associated cost, size and electromagnetic interference (EMI). The on-board oscillator operates at a nominal frequency of 10 kHz. Operation below 10 kHz (for lower supply current applications) is possible by connecting an external capacitor from OSC to ground. The TC7660 is available in 8-Pin PDIP, 8-Pin Small Outline (SOIC) and 8-Pin CERDIP packages in commercial and extended temperature ranges. Features:- • Wide Input Voltage Range: 1.5V to 10V • Efficient Voltage Conversion (99.9%, typ) • Excellent Power Efficiency (98%, typ) • Low Power Consumption: 80 µA (typ) @ VIN = 5V • Low Cost and Easy to Use - Only Two External Capacitors Required • Available in 8-Pin Small Outline (SOIC), 8-Pin PDIP and 8-Pin CERDIP Packages • Improved ESD Protection (3 kV HBM) • No External Diode Required for High-Voltage Specification:- Parameter Specification Supply Voltage 10.5V LV and OSC Inputs Voltage 730 mW Current into LV 20 µA for V > 3.5V Output Short Duration Continuous Package Power Dissipation 730 mW Operating Temperature Range 0°C to 70°C Storage Temperature Range -65°C to 160°C Maximum Junction Temperature 150°C Related Document:- TC7660 IC Data Sheet
