Overview
The AS1349-BWLT3312 is a dual-output synchronous buck switching regulator IC manufactured by ams OSRAM. It provides fixed positive output voltages of 1.2V and 3.3V with maximum output currents of 1.2A and unspecified secondary limits respectively, housed in a 12-WFDFN exposed pad package. The device operates with an input voltage range up to 5.5V and features a 2MHz switching frequency. Designed for surface mount installation, it supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Dual independent output channels providing simultaneous 1.2V and 3.3V regulation
- Synchronous rectification topology for improved efficiency
- Fixed positive output voltage configuration
Applications
- Portable electronic devices requiring multiple power rails
- Embedded systems utilizing low-voltage logic components
- Battery-powered equipment needing efficient DC-DC conversion
Procurement Notes
Verify component authenticity through authorized distributors as the part status is listed as End of Life. Confirm package integrity and pin alignment against the 12-WFDFN specification before integration. Review latest datasheets for any design-in updates or alternative recommendations due to discontinuation status.
Selection Notes
Select this component when dual fixed outputs are required in a compact footprint. Ensure input voltage does not exceed 5.5V. Verify thermal management requirements for the 1.2A output capability within the specified temperature range. Consider availability constraints due to end-of-life status.
Part Context
This IC belongs to the AS13xx series of power management integrated circuits from ams OSRAM. It is categorized under DC-DC switching regulators and PMICs. The specific model targets applications needing space-constrained, multi-rail power solutions with high efficiency characteristics typical of synchronous buck designs.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult manufacturer resources for current alternatives due to the End of Life status.
