Overview
The ATI2202 is a synchronous step-down DC-DC converter from Analog Technologies, Inc. It operates with a fixed switching frequency of 340 kHz and accepts an input voltage range of 4.75 V to 18 V. The device delivers up to 2 A of output current. The output voltage is adjustable, ranging from 0.923 V to 0.9 times the input voltage. It achieves efficiency levels up to 93%. The component is housed in an 8-SOIC package with an exposed pad.
Feature Summary
- Synchronous step-down architecture for high efficiency
- Fixed 340 kHz PWM switching frequency
- Adjustable output voltage capability
Applications
- Battery-powered systems requiring efficient voltage regulation
- Industrial control circuits
- Portable electronic devices
Procurement Notes
Verify the manufacturer designation carefully, as Analog Technologies, Inc. (ATI) is distinct from Analog Devices. Confirm the specific package variant matches your PCB footprint requirements. Ensure the supplier provides official documentation to validate the 340 kHz frequency and 2 A current specifications. Cross-reference the part number against the latest datasheet to confirm RoHS compliance status.
Selection Notes
Select this component when a compact solution is needed for converting 4.75 V to 18 V inputs down to lower voltages. The 340 kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 8-SOIC exposed pad package for thermal management during high-current operation. Verify that the required output voltage falls within the specified 0.923 V minimum limit.
Part Context
Analog Technologies, Inc. specializes in analog and digital electronics, including laser drivers and TEC controllers. The ATI2202 belongs to their DC switching voltage regulator line. It serves as a buck converter solution for applications needing reliable power conversion from moderate input voltages.
Replacement Considerations
Consult official cross-reference lists or contact Analog Technologies directly for verified substitutes. Generic pin-compatible replacements may not match the 340 kHz frequency or 2 A current rating. Verify thermal performance and efficiency curves before substituting.
