LTC3202EMS#TRPBF

LED Driver IC Overview

The LTC3202EMS#TRPBF is a low noise, high efficiency charge pump switching regulator designed for white LED applications. It operates from an input voltage range of 2.7V to 5.5V and provides a regulated output current of up to 125mA. The device utilizes a 10-lead MSOP package with exposed pad for thermal dissipation. It supports PWM dimming control for brightness adjustment and integrates soft-start functionality to limit inrush current during startup.

LED Driver IC Feature Summary

• Integrated switched capacitor charge pump topology for efficient voltage conversion
• Supports pulse-width modulation (PWM) dimming for precise brightness control
• Low noise operation suitable for sensitive analog loads such as white LEDs
• Built-in soft-start mechanism to manage startup inrush currents

LED Driver IC Applications

• White LED backlighting drivers
• Portable electronic device illumination systems
• Battery-powered lighting modules
• High-efficiency DC-DC regulation for low-noise analog circuits

LED Driver IC Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official Analog Devices documentation prior to procurement. Ensure the supplier source is authorized to guarantee component authenticity and traceability. Check for any recent product change notices that may affect pinout or electrical characteristics.

LED Driver IC Selection Notes

Select this component when a compact, low-noise charge pump solution is required for driving white LEDs from a single-cell lithium battery or similar low-voltage source. Consider the 125mA output current limit and the 10-MSOP package size against board space constraints. Evaluate the need for PWM dimming capability versus analog dimming requirements for the specific application design.

LED Driver IC Part Context

This part belongs to the LTC3202 family of charge pump regulators from Analog Devices. It is specifically engineered for applications requiring low electromagnetic interference and stable current regulation. The EMS variant denotes the MSOP package option, while the TRPBF suffix specifies the reel packaging format and lead-free finish.

LED Driver IC Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Cross-reference pinouts and electrical specifications carefully before replacing with other charge pump ICs. Generic equivalents may not match the low-noise performance or specific dimming interface requirements.
