LT3463AEDD#PBF

Overview

The LT3463AEDD#PBF is a dual micropower DC/DC converter featuring boost and charge pump topologies, manufactured by Analog Devices Inc. It operates within an input voltage range of 2.4V to 15V and provides two adjustable outputs ranging from ±1.25V to ±40V. The device delivers up to 180mA for the positive switch and 320mA for the negative switch. Housed in a compact 10-WFDFN package with exposed pad (3mm x 3mm), it supports surface mount installation and functions reliably across a temperature range of 0°C to 70°C.

Feature Summary

Integrates internal Schottky diodes and power switches to minimize external component count
Provides independent control over positive and negative output rails
Features low quiescent current consumption with dedicated shutdown mode
Utilizes fixed off-time current-mode control for stable regulation

Applications

CCD bias voltage generation
LCD bias supply circuits
Handheld computer power management
Digital camera power systems

Procurement Notes

Verify the specific suffix PBF confirms lead-free compliance and RoHS standards before procurement. Confirm the DFN package dimensions match the PCB footprint requirements. Ensure the operating temperature range aligns with the system environment. Validate that the input voltage does not exceed the maximum rating during transient conditions.

Selection Notes

Select this component when dual polarity supplies are required from a single low-voltage source. The LT3463A variant offers higher negative output current compared to the standard LT3463. Consider the small form factor for space-constrained portable designs. Evaluate efficiency requirements as the device optimizes performance at lower load currents.

Part Context

This part belongs to the LT3463 family of micropower converters designed for battery-powered applications. It shares architectural similarities with other Linear Technology PMICs but distinguishes itself through integrated Schottky diodes. The series targets portable electronics requiring efficient dual-rail generation without complex external feedback networks.
