MP2102DQ-LF-Z

Voltage Regulators - DC DC Switching Regulators Overview

The MP2102DQ-LF-Z is a dual-output synchronous step-down switching regulator manufactured by Monolithic Power Systems. It integrates two independent buck converters within a single QFN-10 package, delivering up to 800 mA per channel. The device operates with an input voltage range of 3.5 V to 10 V and provides adjustable output voltages starting from 0.6 V. Key electrical parameters include a switching frequency of 1.24 MHz, which allows for the use of small external inductors and capacitors. The IC features programmable soft-start, cycle-by-cycle current limiting, and thermal shutdown protection. It is designed for high efficiency and compact board space in portable applications.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'DQ-LF-Z' against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Confirm that the QFN-10 package dimensions match your PCB footprint requirements. Check for any recent lifecycle notices such as NRND status before finalizing procurement plans.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a design requires two isolated low-voltage outputs from a single higher-voltage source. It is suitable for applications where space savings are critical compared to using two separate single-channel regulators. Ensure the total load current does not exceed the thermal capabilities of the QFN-10 package under worst-case operating conditions.
