MP9442GJ-P

Voltage Regulators - DC DC Switching Regulators Overview

The MP9442GJ-P is a synchronous step-down converter from Monolithic Power Systems, housed in an 8-pin TSOT-23 package. It supports an input voltage range of 4 V to 36 V and delivers up to 2 A of output current. The adjustable output voltage spans from 800 mV to 33.48 V. Operating at a fixed switching frequency of 600 kHz, the device maintains a quiescent current of 500 uA. It functions reliably within a temperature range of -40 C to +125 C and includes shutdown capability.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout and electrical characteristics match design requirements. Confirm RoHS compliance status through manufacturer documentation before integration. Ensure the TSOT-23-8 footprint aligns with PCB layout constraints. Validate operating temperature ranges against environmental specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is required for converting higher voltages to lower logic or analog rails. The 600 kHz frequency allows for smaller passive components compared to lower frequency alternatives. Consider the 2 A current limit and input voltage ceiling when sizing external inductors and capacitors for the target application load.
