MP156GS

AC DC Converters, Offline Switchers Overview

The MP156GS is a small, energy-efficient offline regulator from Monolithic Power Systems designed for AC/DC conversion applications. It supports Buck, Buck-Boost, and Flyback topologies using Silicon technology. The device operates with a switching frequency of 37 kHz and a maximum duty cycle of 40%. It delivers a fixed output voltage of 12 V at an output current of 150 mA, resulting in a power output of 5 W. The supply voltage range is specified between 5.3 V and 5.6 V, with a quiescent operating current ranging from 2.5 mA to 4.5 mA. It is housed in an SOIC-8 package and functions within a temperature range of -40°C to +125°C.

AC DC Converters, Offline Switchers Procurement Notes

Verify the specific suffix (e.g., -P or -Z) against your Bill of Materials, as these indicate distinct packaging formats such as Reel or Cut Tape. Confirm that the required output voltage and current align with the fixed 12 V / 150 mA specifications. Ensure the design accommodates the non-isolated nature of the component and the specified SOIC-8 thermal requirements.

AC DC Converters, Offline Switchers Selection Notes

Select this component when a fixed 12 V output is required for low-power offline applications. It is suitable for designs utilizing Buck, Buck-Boost, or Flyback topologies where a 37 kHz switching frequency is acceptable. Consider the SOIC-8 package constraints and the -40°C to +125°C operating temperature range during board layout and thermal management planning.
