Overview
The AS1302-BWLT is an inductorless boost converter IC from ams OSRAM, utilizing a double H-bridge charge-pump topology with two external flying capacitors. It operates within an input voltage range of 2.9V to 5.15V and generates a stable fixed output of 5V. The device delivers a maximum output current of 30mA and achieves up to 90% efficiency. Packaged in an 8-UFBGA or WLCSP format, it is designed for compact power management applications requiring efficient voltage step-up without inductive components.
Feature Summary
- Inductorless design using double H-bridge charge-pump topology
- High conversion efficiency up to 90%
- Fixed 5V output generation from variable input
- Compact footprint suitable for space-constrained designs
Applications
- Portable electronic devices requiring voltage boosting
- Battery-powered systems needing stable 5V rails
- Space-limited circuit boards avoiding inductors
Procurement Notes
Verify the specific package variant (UFBGA vs WLCSP) as both are referenced in distributor listings. Confirm the marking code ASQ7 matches your assembly requirements. Check for End-of-Life status or obsolescence notices from ams OSRAM prior to finalizing procurement plans, as availability may be restricted.
Selection Notes
Select this component when inductorless solutions are mandatory due to size constraints. Ensure the application input voltage remains within the 2.9V to 5.15V operational window. Verify that the 30mA load current does not exceed the device's continuous output capability. Consider thermal performance in dense PCB layouts given the small package size.
Part Context
The AS1302 belongs to ams OSRAM's portfolio of switching voltage regulators and power management ICs. It serves as a specialized solution for low-current boost applications where traditional inductive converters are impractical. The series focuses on high-efficiency energy conversion in minimal footprints, targeting modern portable electronics and sensor interfaces.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult ams OSRAM official resources for direct replacements or pin-compatible alternatives.
