Product Summary
The SP682EU-TR is a monolithic charge pump voltage converter that produces a doubled, negative voltage from a single positive supply. The SP682EU-TR charge pump outputs a –10V voltage from a +5V input. Three external charge pump capacitors are required to support the voltage conversion and voltage doubling process. Applications are (1)LCD Display; (2)Negative bias supply for op amps; (3)Serial interface protocol circuits.
Parametrics
SP682EU-TR absolute maximum ratings: (1)VCC: +7V; (2)VOUT: –11V; (3)Storage Temperature: -65°C to +150°C; (4)Power Dissipation: 8-pin NSOIC: 500mW; (5)Package Derating: 8-pin NSOIC: 128 °C/W.
Features
SP682EU-TR features: (1)Low Power Voltage Conversion; (2)+2.4V to +5.5V Input Range; (3)99% Voltage Conversion Efficiency; (4)Typical 60µA Supply Current; (5)Requires Only Three External Capacitors; (6)Includes Low Power Shutdown Option.
