Overview
The LT1913IDD#TRPBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3.6 V to 25 V and delivers a maximum output current of 3.5 A. The device features an adjustable output voltage from 0.79 V to 24.25 V. It supports a switching frequency range of 230 kHz to 2.45 MHz and functions within a junction temperature range of 0°C to 125°C. The component is housed in a 10-WFDFN exposed pad package.
Feature Summary
- Integrates high-side and low-side power switches for efficient synchronous rectification
- Supports programmable switching frequencies up to 2.4 MHz to optimize external component size
- Includes internal soft-start circuitry to limit inrush current during startup
Applications
- Point-of-load regulation for industrial equipment
- Power distribution systems requiring high current density
- Embedded computing platforms needing stable voltage conversion
Procurement Notes
Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the supplier provides valid traceability records for quality assurance purposes.
Selection Notes
Select this component for designs requiring high efficiency at moderate input voltages. The wide frequency adjustment allows optimization between transient response and passive component footprint. Verify thermal management requirements due to the exposed pad package design for heat dissipation.
Part Context
This part belongs to the LT1913 family of buck converters, designed for applications demanding compact solutions. It serves as a direct replacement for legacy non-synchronous regulators while offering improved efficiency. The device complements Analog Devices' portfolio of high-performance power management integrated circuits.
Replacement Considerations
LT1913EDD#PBF: Identical electrical specifications but supplied in tube packaging instead of tape-and-reel format.
