AS1312-BTDM-50

Overview

The AS1312-BTDM-50 is an ultra-low quiescent current hysteretic step-up DC-DC converter manufactured by ams OSRAM. Designed for high efficiency up to 94%, it operates from an input voltage range of +0.7V to +5V. The device provides a fixed output voltage of +5V, with the specific -50 suffix indicating this configuration. It delivers an output current of 0.2A and utilizes a compact surface-mount package suitable for space-constrained portable electronics.

Feature Summary

• Ultra-low quiescent current operation for extended battery life
• Hysteretic control topology for fast transient response
• High conversion efficiency up to 94%
• Wide input voltage range starting at 0.7V

Applications

• Battery-powered portable devices
• Low-voltage sensor modules
• Wearable electronics
• IoT nodes requiring efficient power boosting

Procurement Notes

Verify the exact suffix designation during procurement, as variations such as BTDT may indicate different packaging or binning options while maintaining identical electrical characteristics. Confirm availability status, as supply constraints may affect lead times. Ensure compatibility with your PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when designing circuits powered by single-cell lithium-ion or alkaline batteries where input voltages drop below standard regulator thresholds. The low start-up voltage makes it suitable for applications requiring operation until battery depletion. Consider thermal management needs given the 0.2A output capability in small packages.

Part Context

This part belongs to the AS1312 series of ultra-low IQ boost converters. It is functionally related to variants like the AS1312-BTDT-50, differing primarily in packaging format. The series represents ams OSRAM's solution for maximizing energy extraction from low-voltage sources in portable consumer electronics.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official replacement guides or contact the manufacturer directly for qualified alternatives if end-of-life notifications apply.
