MP2235SGJ-P

Voltage Regulators - DC DC Switching Regulators Overview

The MP2235SGJ-P is a high-efficiency synchronous step-down converter from Monolithic Power Systems. It delivers a continuous output current of 3A with an input voltage range of 4.5V to 16V. The device operates at a fixed switching frequency of 800kHz, which can be synchronized externally between 300kHz and 2MHz. It features low internal power MOSFET on-resistance of 80mΩ and 30mΩ for the high-side and low-side switches respectively. The static current is specified at 500µA. The adjustable output voltage starts from a minimum of 0.8V. It utilizes a TSOT-23-8 package and supports operation within a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'SGJ-P' against the manufacturer's latest documentation to confirm pinout compatibility and RoHS status. Confirm that the component remains in production for existing designs as it is marked not recommended for new designs. Ensure the external soft-start configuration matches the required startup timing specifications before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is required for 3A loads with inputs up to 16V. The 800kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the external soft-start requirement if precise power sequencing is necessary. Evaluate the trade-off between the higher quiescent current of 500µA and the need for synchronous efficiency in your specific application profile.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MPS MP2235 family of synchronous buck converters. It shares architectural similarities with the MP2234 and MP2236 but is distinguished by its 3A current rating and 800kHz switching frequency. The TSOT-23-8 package provides a space-saving footprint suitable for dense PCB layouts. It serves as a legacy option for designs previously utilizing this specific current and frequency combination.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The MP2333H is identified as the recommended alternative for new designs. Verify electrical parameter alignment, particularly the increased switching frequency and different package type (SOT583). Review the updated feature set including power good indication and adjusted input voltage range before substituting.
