Inductorless 5V to -5V Converter

The LTC1046 is a 50mA monolithic CMOS switched capacitor voltage converter. It serves as a replacement for the ICL7660/LTC1044 in 5V applications where higher output current is required. This device is optimized for high current capability with input voltages of 6V or less, sacrificing operating voltage to achieve increased output current. The LTC1046 offers several voltage conversion functions: the input voltage can be inverted (VOUT = µVIN), divided (VOUT = VIN/2), or multiplied (VOUT = ±nVIN). The USA list pricing is intended for budgetary use only, expressed in United States dollars (FOB USA per unit for the specified volume), and is subject to change. International pricing may vary due to local duties, taxes, fees, and exchange rates. For specific volume pricing or delivery quotes, it is advisable to contact a local Linear Technology sales office or authorized distributor. Linear Technology provides many demo boards free of charge to qualified customers; inquiries regarding demo boards should be directed to local sales offices or distributors. Certain demo boards are also available for purchase via credit card on the website. Demo boards are intended for evaluation purposes only, and it is the customer's responsibility to ensure proper and reliable operation in the actual end application.

The LTC1046 is a versatile voltage converter designed for applications requiring efficient power conversion with higher output currents. As a monolithic CMOS device, it integrates a switched capacitor architecture that enables it to perform various voltage conversion tasks. The LTC1046 can invert the input voltage, effectively doubling the output voltage in the negative domain, or it can be configured to divide the voltage by half, providing a stable output for lower voltage requirements. Additionally, it offers the capability to multiply the input voltage by a specified factor, allowing for flexible design implementations in various electronic circuits.

In practical applications, the LTC1046 is particularly well-suited for battery-powered devices and low-voltage systems where maximizing output current is essential. The device's optimized performance at input voltages of 6V or less allows it to be directly integrated into systems with limited voltage headroom while still delivering the necessary current output.

Designers should consider the implications of the LTC1046's operational voltage range when planning circuit layouts. The trade-off between operating voltage and output current must be carefully evaluated to ensure that the device meets the specific requirements of the application. Furthermore, the ability to interface with other components in a circuit, such as microcontrollers or sensors, should be assessed to ensure compatibility.

For those interested in evaluation, Linear Technology offers demo boards which provide a practical means to test the LTC1046's capabilities in real-world scenarios. These boards facilitate a hands-on approach to understanding the device's performance and can assist in the design process. It is recommended that users verify the operational reliability of the LTC1046 in their specific applications, as this is critical to achieving optimal performance in end products.The LTC1046 is a 50mA monolithic CMOS switched capacitor voltage converter. It plugs in for the ICL7660/LTC1044 in 5V applications where more output current is needed. The device is optimized to provide high current capability for input voltages of 6V or less. It trades off operating voltage to get higher output current. The LTC1046 provides sever al voltage conversion functions:the input voltage can be inverted (VOUT = µVIN), divided(VOUT = VIN/2) or multiplied (VOUT = +/-nVIN). * The USA list pricing shown is for BUDGETARY USE ONLY, shown in United States dollars (FOB USA per unit for the stated volume), and is subject to change.
