MIC9130YQS

Overview

The MIC9130YQS is a current-mode PWM controller manufactured by Microchip Technology, designed for efficient conversion of -48V telecom voltages to logic levels. It operates with a switching frequency of 2.5 MHz and supports boost and buck topologies. The device provides one output with a maximum current of 1 A and a maximum duty cycle of 50%. It functions within an operating temperature range of -40°C to +125°C and is housed in a 16-pin QSOP package.

Feature Summary

• Current-mode PWM control architecture for efficient voltage conversion
• Optimized for converting -48V telecom inputs to logic level outputs
• Supports both boost and buck converter topologies

Applications

• Telecom DC/DC power supply systems
• Voltage regulation for logic level translation from telecom rails
• Industrial power management modules

Procurement Notes

Verify the specific suffix (YQS) against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Ensure the package type matches the QSOP-16 footprint requirements for your PCB design. Cross-reference the RoHS status and lead-free designation with the latest production documentation to ensure regulatory compliance for your target market.

Selection Notes

Select this component when designing power stages that require stepping down or up from standard -48V telecommunications infrastructure voltages. The high switching frequency allows for smaller external passive components compared to lower-frequency controllers. Consider the thermal performance within the specified -40°C to +125°C range if operating in harsh industrial environments.

Part Context

This part belongs to the MIC9130 family of switching controllers from Microchip Technology. It is specifically engineered for telecom applications where reliable conversion of negative voltage rails is required.
