MIC23050-SYML-TR

Voltage Regulators - DC DC Switching Regulators Overview

The MIC23050-SYML-TR is a synchronous buck switching regulator from Microchip Technology's HyperLight Load series. It provides a fixed 3.3V output with a maximum current of 600mA. The device operates within an input voltage range of 2.7V to 5.5V and features a 4MHz switching frequency. It utilizes an 8-MLF package (2x2mm) with an exposed pad for thermal management. The component supports operation across a junction temperature range of -40°C to 125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• HyperLight Load technology enables high efficiency at light loads by transitioning between PFM and PWM modes.
• Integrated synchronous rectification reduces external component count and improves power conversion efficiency.
• Fixed 3.3V output simplifies design implementation for standard logic supply rails.

Voltage Regulators - DC DC Switching Regulators Applications

• Portable battery-powered consumer electronics
• Embedded systems requiring efficient step-down regulation
• IoT devices with strict power budget constraints

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix SYML against the official datasheet to confirm the 3.3V fixed output and 8-MLF package configuration. Ensure compatibility with RoHS3 standards and check for any recent Product Change Notifications regarding manufacturing location or packaging updates before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3V rail is required from a 2.7V–5.5V source. The 4MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider the 600mA limit for load requirements and ensure adequate thermal dissipation via the exposed pad on the 8-MLF footprint.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MIC23050 family, designed for space-constrained applications. It replaces older Micrel-branded equivalents following Microchip's acquisition. The HyperLight Load feature distinguishes it from standard buck regulators by optimizing quiescent current during low-load conditions.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

MIC23050-GYML-TR offers a similar topology but provides a fixed 1.8V output instead of 3.3V. Verify that the target circuit voltage requirement matches the replacement's fixed output specification before substitution.
