LT3463AEDD#PBF

Product Overview

The LT3463AEDD#PBF from Analog Devices Inc. is a surface-mount step-up switching regulator that generates positive and negative adjustable output rails. It uses a boost and charge pump topology with two outputs, accepting a 2.4 V to 15 V input and providing output voltages from ±1.25 V to ±40 V. The 10-WFDFN exposed-pad package supports 0°C to 70°C ambient operation.

Key Features

• Boost and charge pump topology for step-up conversion
• Positive and negative dual-rail output with two adjustable outputs
• Input voltage range of 2.4 V to 15 V
• Adjustable output range from ±1.25 V to ±40 V
• 180 mA and 320 mA switch current ratings
• 10-WFDFN exposed-pad surface-mount package, 10-DFN (3x3) designation
• No synchronous rectifier

Applications

• Generating bipolar supply rails for op-amp and analog signal conditioning circuits
• Adjustable positive and negative output supplies for portable measurement instruments
• Dual-rail biasing for sensor and transducer interface circuits

Design & Procurement Notes

Designers should confirm that the input voltage, output voltage, and switch current ratings remain within the 2.4 V to 15 V input range, ±1.25 V to ±40 V output range, and 180 mA and 320 mA switch current ratings. The 10-WFDFN exposed-pad package and 0°C to 70°C ambient range should be considered for surface-mount layout and enclosure environment. The absence of synchronous rectification and the adjustable dual-rail topology should be considered in the power supply design.
