Overview
The ATI1934 is a wide input range, high-efficiency DC-to-DC step-down switching regulator from Analog Technologies. It delivers up to 600mA output current with an adjustable voltage range starting at 0.8V and a maximum output of 20V. The device operates with a fixed switching frequency of 1.2MHz and features synchronous rectification for improved performance. It supports an input voltage range of 5V to 42V and functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Synchronous rectification design for enhanced efficiency
- Wide input voltage capability supporting 5V to 42V sources
- High-frequency operation at 1.2MHz for compact external component sizing
Applications
- Battery-powered portable electronics requiring efficient step-down conversion
- Industrial control systems operating within wide input voltage ranges
- Embedded systems needing regulated low-voltage power supplies
Procurement Notes
Verify the specific package variant, as the ATI1934 is available in SOT-23-6 configurations. Confirm that the supplier provides official datasheets matching Analog Technologies documentation. Ensure compatibility with your system's thermal requirements given the -40°C to +85°C operating range. Request batch traceability if required for industrial or automotive-grade applications.
Selection Notes
Select this component when a wide input voltage range up to 42V is required alongside high efficiency. The synchronous design makes it suitable for applications where power conservation is critical. Consider the 1.2MHz switching frequency for designs prioritizing smaller inductor sizes. Ensure the load current does not exceed the 600mA limit under all operating conditions.
Part Context
This part belongs to the family of buck switching regulators designed for general-purpose DC-DC conversion. It integrates the control logic and power switches into a single IC, reducing board space compared to discrete solutions. The ATI1934 targets applications requiring reliable regulation from varying input sources.
Replacement Considerations
Check for direct pin-compatible alternatives from Analog Technologies or other manufacturers offering similar 600mA synchronous buck regulators. Verify that substitute parts maintain the 1.2MHz frequency and 5V-42V input range to ensure circuit compatibility without redesign.
