MIC23250-F4YMT-TR

Voltage Regulators - DC DC Switching Regulators Overview

The MIC23250-F4YMT-TR is a dual synchronous buck switching regulator manufactured by Microchip Technology. It features Hyper Light Load mode for high efficiency at light loads, consuming only 33µA quiescent current when operating both outputs. The device supports an input voltage range of 2.7V to 5.5V and provides two independent output channels with fixed voltages of 1.2V and 1.8V. Each channel delivers up to 400mA of output current. Operating at a 4MHz switching frequency, it utilizes a TMLF-10 package suitable for surface mount installation.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix F4YMT against official Microchip documentation to confirm pinout and electrical characteristics, as variations exist within the MIC23250 family. Ensure compatibility with the required 1.2V and 1.8V fixed outputs. Confirm the TMLF-10 package availability and reel quantity requirements from authorized distributors. Cross-reference the manufacturer part number to avoid confusion with similar models like the MIC23250-M4YMT-TR.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing systems requiring two distinct low-voltage rails (1.2V and 1.8V) from a single 2.7V-5.5V source. The 4MHz frequency allows for smaller external inductors and capacitors compared to lower-frequency alternatives. The Hyper Light Load feature is critical for battery-operated devices where standby current consumption must be minimized. Ensure the thermal performance of the TMLF-10 package meets the system's heat dissipation requirements under maximum load.
