AS1337B-BTDT

Overview

The AS1337B-BTDT is a synchronous boost switching regulator IC manufactured by ams OSRAM. It operates with an input voltage range of 0.65V to 4.5V and provides an adjustable output voltage between 2.5V and 5V. The device delivers a maximum switch current of 850mA at a fixed switching frequency of 1.2MHz. It features a single positive output configuration and includes integrated synchronous rectification for improved efficiency. The component is housed in an 8-TDFN (3x3mm) package with an exposed pad, designed for surface-mount installation.

Feature Summary

Integrated synchronous rectification for enhanced power conversion efficiency
Adjustable output voltage capability within specified limits
Compact surface-mount packaging suitable for space-constrained designs

Applications

Portable electronic devices requiring efficient step-up power regulation
Battery-powered systems utilizing lithium-ion or polymer cells
Embedded circuits needing stable voltage from low-input sources

Procurement Notes

Verify the End-of-Life status before design finalization, as this component may be discontinued. Confirm that the 8-TDFN footprint matches your PCB layout requirements. Ensure compatibility with the 0.65V minimum input voltage for your specific power source. Check for available replacement alternatives if long-term supply stability is required for production.

Selection Notes

Select this component when a compact synchronous boost converter is needed for inputs starting as low as 0.65V. The 850mA current rating suits moderate load applications. Consider the 1.2MHz switching frequency for smaller external passive components. Verify that the 2.5V to 5V adjustable output range aligns with downstream circuit requirements.

Part Context

This part belongs to the AS1337 series of power management ICs from ams OSRAM. It is categorized under DC-DC switching regulators within the PMIC family. The device is specifically engineered for boost topology applications, distinguishing it from buck or buck-boost variants in the manufacturer's portfolio.
