Overview
The AS1383-BWLT-45 is a synchronous step-up DC-DC converter manufactured by ams OSRAM. It operates with an input voltage range of 2.7 V to 5.5 V and delivers a fixed output voltage of 4.5 V at up to 200 mA. The device integrates a 3.5 MHz switching frequency and features a shutdown function for power management. It is housed in a WLCSP-6 package, suitable for surface mount applications. The component supports operation within a temperature range of -40°C to +85°C and draws a quiescent current of 25 µA.
Feature Summary
- Synchronous rectification architecture for improved efficiency
- Integrated shutdown control for low-power standby modes
- Compact wafer-level chip-scale packaging design
Applications
- Portable electronic devices requiring efficient voltage boosting
- Battery-powered sensor modules
- Mobile communication equipment
- IoT nodes with limited power budgets
Procurement Notes
Verify the specific suffix designation against official datasheets to confirm electrical characteristics and pinout compatibility. Confirm RoHS compliance status and lead-free soldering requirements prior to integration. Ensure that the WLCSP-6 footprint matches the target PCB layout constraints. Validate thermal performance under maximum load conditions within the specified operating temperature range.
Selection Notes
Select this component when a fixed 4.5 V output is required from a single-cell lithium-ion or similar battery source. The synchronous topology offers better efficiency compared to non-synchronous alternatives at moderate loads. Consider the small form factor for space-constrained designs. Evaluate the 3.5 MHz switching frequency for EMI management and passive component size reduction.
Part Context
This part belongs to the AS1383 series of switching voltage regulators. It is designed as a compact power management solution for mobile and portable applications. The series utilizes advanced CMOS technology to achieve high efficiency in a minimal footprint. It serves as a key component in systems requiring reliable step-up conversion from low input voltages.
Replacement Considerations
AS1383-BWLM-45 is a documented variant within the same product family. Verify if the suffix change indicates differences in internal configuration or testing criteria. Cross-reference pinouts and electrical parameters before substitution.
