MP1469GJ-P is a DC DC switching regulator ideal for powering green applications with demanding voltage and current requirements. These include: industrial applications such as Uninterruptible Power Supplies (UPSs). energy management systems like solar or wind power, HVAC/R (Heating, ventilation and air conditioning/refrigeration) systems, street lighting systems and other transportation systems.MP1469GJ-P is also suitable for embedded applications such as power adapters, network infrastructure, as well as Point-of-Load (POL) converters for industrial automation and digital home multimedia equipment.

MP1469GJ-P Working Principle

MP1469GJ-P is a DC DC switching regulator that uses a buck-boost topology to convert a wide input voltage range (4.5V to 40V) into a low output voltage (1.2V to 40V). The MP1469GJ-P works by comparing the feedback voltage with a reference voltage to regulate the output voltage of the buck-boost converter.When the output voltage is lower than the feedback voltage, the PWM controller uses the PWM signal to regulate the on-time of the high-side and low-side MOSFETs to boost the output voltage. Conversely, when the output voltage is higher than the feedback voltage, the PWM controller uses the PWM signal to regulate the on-time of the high-side and low-side MOSFETs to buck the output voltage. The MP1469GJ-P also uses pulse frequency modulation (PFM) to conserve energy in light load conditions.

Features of MP1469GJ-P

The MP1469GJ-P has several features that make it an ideal choice for powering green applications. It has a wide 4.5V to 40V input voltage range and a wide 1.2V to 40V output voltage range.
