R12P09D/P

DC DC converters are devices designed to convert input voltage to a stabilized output voltage, by converting either from low voltage, high current to a higher voltage, lower current or from high voltage, low current to a lower voltage, higher current. This DC/DC conversion technology is used in many electronics appliances, including smartphones, laptops and tablets. The R12P09D/P converter series is manufactured by Vicor Corporation and is used to convert 12 V dc input to 9V dc output.

The R12P09D/P converter consists of two main components, namely the switching regulator and the output transformer. The switching regulator part consists of an integrated circuit (IC), which performs the switching, and the driver transistor, which drives the switching action. This in turn controls a power transformer with a secondary winding that produces the 9V dc output.

The purpose of a high power DC to DC converter is to regulate and convert the output voltage from one level to another. To regulate the voltage, a switching regulator is used. It switches between two different actionable states, known as on and off, in order to control the output voltage. The on-state allows current to flow from the input and the off-state prevents current flow from the input. A circuit of comparators is used to detect any voltage drop or voltage surge from the input voltage and react accordingly to control the output voltage by adjusting the action states.

The R12P09D/P converter allows a wide input voltage range of 7V to 18V, with a wide temperature range from -40°C to +90°C. It has an output voltage of 9V with an astonishing efficiency of nearly 95% at full-load. The input ripple current is usually between 1.8A and 150mA & the switching frequency of the power transformer is set to 65KHz. This power converter is very reliable and contains several short circuit protection functions, including current or cycle slew-rate limiting, dead-time control, soft-start, over-voltage protection, under-voltage protection and temperature shutdown.

The primary application of R12P09D/P converter is to convert input voltage for switching mode power supplies. They are used to power up medium and high-end digital consumer electronic products such as smartphones, tablets, and gaming consoles. They are also used to power up low-end portable electronics like personal digital assistants and MP3 players that require large currents. R12P09D/P converters are also used in offices where computing equipment needs to use higher voltage supplies for regulation or regulation-less supplies.

The R12P09D/P converter from Vicor Corporation exhibits excellent performance characteristics, making it ideal for a wide range of DC/DC conversion applications. Its various protection mechanisms make it exceptionally reliable. Its wide temperature and input voltage range give it the flexibility needed to operate in a variety of conditions, making it the perfect choice for industry-leading performance across a range of applications.
