Overview
The LT1683EG#PBF is a switching regulator controller designed to minimize conducted and radiated electromagnetic interference. It utilizes a push-pull topology with a single output, supporting an input voltage range of 4 V to 20 V. The device delivers a fixed 5 V output at 10 mA maximum current. Key electrical specifications include a static current of 24 uA, a switch frequency adjustable between 20 kHz and 250 kHz, and a shutdown feature. It operates within a temperature range of -40 C to +125 C and is housed in an SSOP-20 package.
Feature Summary
- Designed to lower conducted and radiated electromagnetic interference for ultralow noise performance
- Features a push-pull topology suitable for DC/DC control applications
- Includes a shutdown capability for power management efficiency
Applications
- Electromagnetic interference sensitive power systems
- Ultralow noise DC/DC converter designs
- Push-pull switching regulator implementations
Procurement Notes
Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the SSOP-20 package dimensions match your PCB footprint requirements. Ensure the operating temperature range of -40 C to +125 C aligns with your environmental conditions. Check for any recent product change notices that may affect pinout or electrical characteristics.
Selection Notes
Select this component when minimizing electromagnetic interference is critical for system performance. The push-pull topology requires appropriate external drive components for optimal operation. Consider the 20 kHz to 250 kHz frequency range when selecting passive components for the power stage. Verify that the 4 V to 20 V input range covers your supply variations.
Part Context
This part belongs to the LT1683 series from Analog Devices, specifically engineered as a DC/DC controller. It is distinct from standard regulators by its focus on EMI reduction through controlled switching techniques. The EG#PBF designation specifies the industrial temperature grade and lead-free packaging format.
Replacement Considerations
Consult official Analog Devices documentation for verified substitute part numbers. Cross-reference pinouts and electrical parameters carefully when considering alternatives.
