LTC3217EUD#PBF

LED Driver IC Overview

The LTC3217EUD#PBF is a multi-LED camera light driver IC manufactured by Analog Devices Inc. It utilizes a switched capacitor charge pump topology to regulate LED current. The device features four independent outputs, each capable of delivering up to 150 mA. It operates within an input voltage range of 2.9 V to 4.5 V and supports PWM dimming for brightness control. The component is housed in a 16-QFN (3x3) surface-mount package with an exposed pad.

LED Driver IC Feature Summary

• Integrates a switched capacitor charge pump for efficient LED regulation
• Provides four independent output channels for multi-LED applications
• Supports PWM dimming functionality for precise brightness control

LED Driver IC Applications

• Camera flash lighting systems
• Multi-LED indicator circuits
• Display backlighting drivers

LED Driver IC Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS status. Confirm the QFN-16 package dimensions match your PCB footprint requirements. Check for obsolescence notices as this part may be discontinued or superseded by newer revisions. Ensure thermal relief pads are designed correctly for the exposed pad connection.

LED Driver IC Selection Notes

Select this component when four synchronized LED channels are required from a single supply rail. The 150 mA per channel limit suits low-to-medium power LED arrays. Consider the 2.9 V minimum input voltage for battery-powered designs. Verify that the charge pump topology meets efficiency requirements compared to inductive solutions.

LED Driver IC Part Context

This part belongs to the LTC3217 family of LED drivers. It shares architectural similarities with the LTC3210 but offers four outputs instead of five. The EUD suffix denotes the specific 16-QFN package variant. It is designed for portable electronics requiring compact power management solutions.

LED Driver IC Replacement Considerations

LTC3217EUD#TRPBF is available in tape-and-reel packaging for automated assembly. Direct functional substitutes require matching 4-channel charge pump architecture and 150 mA output capability.
