MPM3805GQB-P

Product Overview

The MPM3805GQB-P from Monolithic Power Systems Inc. is an active, non-isolated point-of-load module DC-DC converter with one output. It accepts an input voltage from 2.5 V to 6 V and provides an output from 0.6 V to 6 V at up to 600 mA. The surface-mount 12-PowerVFQFN module measures 3.0 mm x 2.5 mm x 0.9 mm, with a supplier device package listed as 12-QFN (3x2.5), and is specified for operation from -40°C to 125°C. The converter lists OCP, OTP, and UVLO features and an active-high enable control.

Key Features

• Non-isolated point-of-load topology with a single output
• Input voltage range of 2.5 V to 6 V
• Output voltage range of 0.6 V to 6 V at 600 mA maximum
• Listed protection features include OCP, OTP, and UVLO
• Surface-mount 12-PowerVFQFN module with active-high enable
• Supplier device package listed as 12-QFN (3x2.5)

Applications

• Commercial information technology equipment
• Local regulation for board-mounted loads requiring 0.6 V to 6 V
• Enable-controlled power sequencing for low-current subsystems

Design & Procurement Notes

Designers should verify that the required output current remains within 600 mA and that the input supply stays within 2.5 V to 6 V under all conditions. Because the module is non-isolated, the output cannot be assumed to provide galvanic separation from the input. The active-high enable control can be used for local power sequencing or standby control, while OCP, OTP, and UVLO support protection behavior. The 3.0 mm x 2.5 mm x 0.9 mm surface-mount package requires layout and thermal evaluation at the specified -40°C to 125°C operating range. The part is listed as Active.
