Description
The MP175L is a primary-side regulator that provides accurate constant-voltage (CV) regulation without an optocoupler. The MP175L supports buck, buck-boost, boost, and flyback topologies. The MP175L has an integrated 700V MOSFET and high-voltage current source to simplify the structure and reduce costs.
The MP175L is a green-mode operation regulator. Both the peak current limit (ILIMIT) and switching frequency (fSW) decrease with decreasing load. This feature provides excellent efficiency under light-load conditions and improves the overall average efficiency.
The MP175L has multiple protection features, including over-temperature protection (OTP), VCC under-voltage lockout (UVLO), overload protection (OLP), short-circuit protection (SCP), brown-in protection, and open-loop detection (OLD).
These features make the MP175L an ideal regulator for offline, low-power applications, such as home appliances and standby power. The MP175L is available in an SOIC-8 package.

ARTICLE
AUDIBLE POWER SUPPLY NOISEARTICLEThe design requirements of today’s switching power supplies are driven by efficiency requirements not only at full load, but also under sleep mode or no-load conditions when the cable is disconnected. Power system integrators have to meet new regulations from agencies such as Energy Star, 80 Plus, and the European Commission’s CoC, regardless of the power supply’s load condition....

USES, ADVANTAGES, AND WORKING PRINCIPLES OF A SWITCHING POWER SUPPLYARTICLEA power supply is an electrical device that converts the electric current that comes from a power source to the voltage value necessary for powering a load, like a motor or an electronic device. There are two main designs for power supplies: a linear power supply and a switching power supply. For many years, linear AC/DC power supplies have been transforming AC power from the utility grid ...
