AS3630-ZWLM

Overview

The AS3630-ZWLM is an LED lighting driver IC manufactured by ams OSRAM, designed for high-performance illumination applications. It features a single output capable of delivering up to 8A of current, making it suitable for driving high-power LEDs. The device operates with a switching frequency of 4MHz and includes a 10-bit ADC for precise control and monitoring. It supports supercapacitor-based energy storage solutions and utilizes a WL-CSP-25 package for compact integration. The component functions within a temperature range of -30°C to +85°C and is rated for a supply voltage of 3.7V.

Feature Summary

• Integrates a 10-bit analog-to-digital converter for accurate system monitoring and feedback.
• Supports supercapacitor charging and management for reliable power backup or peak load handling.
• Features a high-frequency 4MHz switching operation to minimize external passive component size.
• Delivers high output current capability up to 8A for demanding LED loads.

Applications

• High-power LED street lighting systems
• Industrial area lighting fixtures
• Supercapacitor-backed emergency lighting circuits
• Compact high-bay LED luminaires

Procurement Notes

Verify the exact suffix 'ZWLM' against official ams OSRAM documentation to confirm pinout and thermal pad configuration differences from similar variants like ZWLT. Check current lifecycle status as some AS3630 variants are marked as obsolete. Ensure the supplier provides valid RoHS compliance certificates. Confirm that the WL-CSP-25 package availability matches your assembly capabilities. Request full datasheet access before finalizing design-in to verify electrical characteristics.

Selection Notes

Select this component when designing LED drivers requiring high current output in a small footprint. The 4MHz frequency allows for smaller inductors and capacitors compared to lower-frequency alternatives. The integrated 10-bit ADC simplifies calibration and fault detection without additional microcontroller overhead. Consider the -30°C to +85°C operating range for industrial or outdoor environments. Evaluate the need for supercapacitor support if backup power or surge protection is required in the application.
