Overview
The LT1576CS8-5SYNC#PBF is a monolithic buck mode switching regulator manufactured by Analog Devices Inc. It integrates a 1.5A power switch and operates at a fixed frequency of 200kHz. The device provides a positive fixed output voltage of 5V with a maximum output current of 1.5A. It accepts an input voltage range from 5V to 25V. The component features a shutdown function and operates within a temperature range of -40°C to +125°C. It is housed in an 8-SOIC package.
Feature Summary
- Integrates a 1.5A power switch on the die for compact design
- Fixed 200kHz switching frequency reduces external component size
- Includes internal oscillator and control circuitry
- Supports shutdown mode for power management
Applications
- Battery-powered systems requiring efficient step-down conversion
- General-purpose DC-to-DC power supplies
- Pre-regulation for linear regulators
- Portable electronic devices
Procurement Notes
Verify the specific suffix SYNC against official Analog Devices documentation to confirm pinout or functional variations, as suffixes can indicate manufacturing changes. Confirm RoHS compliance status through the manufacturer's current datasheet. Check lifecycle status, as this part may be obsolete or limited supply. Ensure the 8-SOIC package dimensions match your PCB footprint requirements before ordering.
Selection Notes
Select this component when a fixed 5V output is required from an input range of 5V to 25V. It is suitable for applications needing up to 1.5A continuous current with moderate efficiency needs. Consider the 200kHz frequency for balancing EMI and filter component size. Evaluate thermal performance in the SOIC-8 package for high ambient temperatures.
Part Context
This part belongs to the LT1576 series of switching regulators. It is a variant of the LT1576 family, specifically configured for a fixed 5V output. The CS8 designation indicates the commercial temperature grade and SOIC-8 package. The #PBF suffix denotes lead-free packaging compliant with environmental standards.
Replacement Considerations
LT1576CS8-5#PBF: Direct equivalent without SYNC suffix variation. LT1576IS8-5#PBF: Industrial temperature grade version. LT1576CS8#TRPBF: Tape and reel packaging variant.
