Overview
The LT1765EFE#PBF is a monolithic buck switching regulator manufactured by Analog Devices Inc., housed in a 16-TSSOP-EP package. It operates with an input voltage range of 3 V to 25 V and delivers up to 3 A output current. The device features a fixed 1.25 MHz switching frequency, adjustable output voltage from 1.2 V to 22.5 V, and low quiescent current of 15 uA. It supports shutdown functionality and functions within a temperature range of -40°C to +125°C TJ.
Feature Summary
- Integrates a high-efficiency power switch capable of delivering 3 A continuous load current.
- Utilizes a fixed 1.25 MHz switching frequency to minimize external component size.
- Includes internal compensation for stable operation across various output configurations.
- Features a shutdown pin to significantly reduce standby power consumption.
Applications
- Point-of-load regulation for embedded systems
- Battery-powered equipment requiring efficient step-down conversion
- Industrial control systems with wide input voltage ranges
Procurement Notes
Verify the specific suffix #PBF indicates lead-free compliance and tube packaging when ordering. Confirm that the EFE variant corresponds to the TSSOP-EP package type required for your PCB layout. Ensure compatibility with the 1.2 V minimum output voltage setting during design validation.
Selection Notes
Select this component when a compact solution is needed for high-current applications without synchronous rectification. The fixed frequency simplifies EMI filtering compared to variable frequency converters. Consider thermal performance in the TSSOP-EP package if operating near maximum current limits.
Part Context
This part belongs to the LT1765 family of non-synchronous buck regulators. It shares architectural similarities with other LT176x series devices but offers specific output voltage adjustability and current capabilities distinct from fixed-voltage variants like the LT1765EFE-5.
Replacement Considerations
LT1765EFE-5#PBF provides a fixed 5 V output instead of adjustable voltage. LT1765EFE-3.3#PBF offers a fixed 3.3 V output. Both share identical pinouts and electrical characteristics except for the output voltage setting mechanism.
