MIC23450-AAAYML-T5

Voltage Regulators - DC DC Switching Regulators Overview

The MIC23450-AAAYML-T5 is a high-efficiency, triple-channel synchronous buck regulator from Microchip Technology. It features three independent output channels, each capable of delivering up to 2A of continuous current. The device operates with a fixed switching frequency of 3MHz and utilizes Pulse Width Modulation (PWM) for regulation. It incorporates Hyper Light Load mode to maintain high efficiency at light loads while providing ultra-fast transient response. The input voltage range spans from 2.7V to 5.5V, supporting adjustable output voltages down to 1V. It is housed in a compact 26-pin QFN package.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix AAYML-T5 against the manufacturer's official datasheet to confirm pinout compatibility and thermal specifications. Ensure the ordering code matches the exact reel quantity and tape-and-reel packaging requirements specified in the latest production documentation before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when multiple isolated low-voltage rails are required from a single input source. The 3MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the total load current across all three channels does not exceed the individual channel limits and that the PCB layout supports the thermal dissipation requirements of the QFN package.
