LTC3260EDE#PBF

Voltage Regulators - Linear + Switching Overview

The LTC3260EDE#PBF is a low-noise, high-voltage dual polarity output power supply IC manufactured by Analog Devices Inc. It utilizes a charge pump topology to generate positive and negative outputs from a single input voltage source. The device operates with an input voltage range of 4.5V to 32V and provides two fixed output configurations: -Vin and +2Vin. It supports a maximum output current of 100mA per rail. The switching frequency is adjustable between 50kHz and 500kHz. The component is housed in a 20-TSSOP package with an exposed pad and is rated for operation over a temperature range of -40°C to 150°C.

Voltage Regulators - Linear + Switching Procurement Notes

Verify the specific suffix EDE against the manufacturer's official datasheet to confirm the package type (DFN-12 vs TSSOP) and temperature grade. Ensure the ordering part number matches the exact electrical specifications required for the design. Cross-reference the RoHS compliance status and material declaration documents provided by Analog Devices prior to final procurement decisions.

Voltage Regulators - Linear + Switching Selection Notes

Select this component when a compact solution for generating both positive and negative voltages from a single unregulated or regulated source is required. Consider the 100mA output current limit and the input voltage range up to 32V. Evaluate the need for low noise characteristics versus other charge pump alternatives. Verify that the 20-TSSOP or DFN-12 package footprint fits the PCB layout constraints.

Voltage Regulators - Linear + Switching Part Context

The LTC3260 belongs to Analog Devices' family of low-noise charge pump regulators. It is designed to replace bulky transformer-based solutions or multiple discrete regulator stages. The device integrates all necessary control logic and power switches into a small surface-mount package, simplifying the design of dual-supply systems in space-constrained applications.

Voltage Regulators - Linear + Switching Replacement Considerations
