MP28310GC-Z Equivalent & Substitute Parts

Part Overview

The MP28310GC-Z is an active Power Management Integrated Circuit (PMIC) manufactured by Monolithic Power Systems Inc. This device functions as a dual-output voltage regulator combining a Step-Down (Buck) converter and a Linear (LDO) regulator topology. The MP28310GC-Z operates across a 2V to 5.5V supply voltage range with a switching frequency of 1.5MHz, delivering 300mA from the primary output and 100mA from the secondary output. The device is housed in a 12-CSP (1.2x1.6mm) package suitable for space-constrained surface mount applications.

The MP28310GC-Z maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified based on matching electrical specifications, output configurations, and package compatibility to ensure direct functional equivalence in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP28310GC-Z are identified based on strict parameter matching across the following critical criteria:

Topology Match: Both the main part and substitute must implement identical dual-output architecture with one Step-Down (Buck) converter and one Linear (LDO) regulator.

Output Configuration: Output 1 must support the same voltage options (1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 3V, 3.3V) at 300mA current rating. Output 2 must support 1.8V, 2.8V, 3V at 100mA.

Electrical Specifications: Supply voltage range (2V ~ 5.5V), switching frequency (1.5MHz), and operating temperature range (-40°C ~ 125°C) must be identical.

Package Compatibility: The 12-CSP (1.2x1.6mm) package designation must match exactly to ensure PCB footprint compatibility.

Compliance & Status: Both parts must maintain Active product status with RoHS3 compliance, MSL 1 rating, and REACH Unaffected designation.

The MP28310GC-P qualifies as a parametric equivalent substitute based on complete alignment with all specified parameters.
